In the first part, let’s talk about ordinary DVD drives.

Generally speaking, there are very few computers that are not equipped with a CD-ROM drive, otherwise it will be troublesome to install the system. As for some rightists who shout the slogan that CD-Rom is enough, it is certainly comparable to the frog in the well. Now in the majority of Most of the pirated copies in the city are DVDs (as are data certificates), so it’s better not to buy a CD drive.

First of all, optical drives are relatively untechnical products, and few of them are made by themselves. Large manufacturers generally hire OEMs for their optical drives, and you can tell about their own products just by looking at the OEM. Some people are unconvinced and say that Foxconn's motherboards can be compared with Asus's motherboards. Of course they can't. Motherboards have technology. Asus and the like do the design, produce their own design drawings, and require their own components. The foundry is just an assembler. Role, even so, the quality control requirements are very high, so I agree that the motherboard industry is naive when it comes to OEM (forget it about domestic seven-XX OEMs), but for something as common as an optical drive, there are no requirements. There are so many, and the OEM level is very low. Generally, there is not much difference between OEM products except for the panel. Therefore, optical drive experts can generally guess who OEMed them at a glance. Some people also ask whether it is like LCD monitors. "OEM" (panel manufacturers are more accurate) often changes. Optical drives do not fluctuate as much as LCD panels. Even if they are replaced, more rigorous manufacturers will also change the model. . In addition, there are also rumors that the quality of different OEM brands produced by the same assembly line is different. In fact, it is a sour grape mentality. The good ones are the brands they are superstitious about, and the bad ones are the brands they do not believe in. At least, this kind of rookie level "knowledge" It has been around since the era of CD drives. Unfortunately, there is no evidence yet. I can’t say anything about it. On the contrary, it is credible that the OEM quality is exactly the same. Because there are countless disassembly pictures on the Internet, you can observe the details, and the general firmware (Firmware, also known as firmware) can be mutually brushed, and the official generally admits it readily.

There are many brands of optical drives. Taking the well-known ones as an example, I personally feel that the optical drives are not much different. The disk reading ability and lifespan are not as good as those of the previous era. However, the price is also in front of you. There is nothing to say, so I recommend that the optical drive be a little bit better. Forget it. Teclast, Samsung, LG, Benq, and Pioneer (note, I am patriotic, this article is just a technical article) are not much different. Some people use it for a month and it fails, and some people use it for two years and it doesn’t fail. Don’t worry about it. . Moreover, the optical drive should not be greedy for disk reading ability. Long life is the key. The problem of not being able to read a street movie is not a big problem. The poor quality of the pirated disc itself is also the reason. But at the critical moment, even the well-engraved XP installation disk cannot be installed. It's troublesome. Of course, the lifespan of an optical drive is also related to the usage method and frequency, environment, hardware power supply, and whether it is fake or returned for repair. The luck factor is really big. By the way, since the maximum speed is only 16X, there is no big difference in the speed of the optical drive, and disc explosions are unlikely to occur. However, for the sake of selling points, many manufacturers of optical drives promote the creation of "disk reading kings", often sacrificing lifespan, because the quality of disc reading is basically a bald head, and the same In order to improve disk reading, you need to dynamically increase the power of the optical head (generally DVD drives are Sanyo, Pioneer, and Philips). This is very bad. The optical head is inherently fragile, so usually the better the disk reading ability, the more likely it will fail. The faster the time. By the way, there is also the matter of region locking, which is a good thing. CD-ROM drives sold to developed countries are basically region-locked (RPC-II regulations). Besides, I haven’t bought a disc that requires a region change in several years. It doesn't matter. In short, first of all, the optical drive is not much different, secondly, the disk reading ability is not even counterproductive, and thirdly, it is boring to worry about zone locking.

Now I will talk about the most famous ordinary optical drives:

1. Pioneer, Pioneer’s optical drives used to be very good or even the best, such as the most famous 121SA (early It has been discontinued, and even if it is available now, it is mostly for repair). I remember that it was more than 400 when I bought it, and the price was more than half higher than that of its peers. The suction cup type is also very cute, but except for the extremely slow disk recognition and poor disc compatibility, everything else is very good (note the era 121 was in). Later, due to the price reduction of DVDs, profits plummeted. Therefore, there is a big price reduction from Pioneer. Unfortunately, many experts are too nostalgic and always emphasize Pioneer DVD on the equipment list.

At present, several Pioneer successor models such as 122 and 123, in order to reduce the price, even the control chip has been changed from Panasonic (MN103S71) to ali, MTK (MediaTek's MT1355PE), and has become a short body (with 2M cache) category is very minor), has shrunk significantly? Note that since you don’t need to worry about lens and other technologies with optical heads, current Sanyo, Pioneer and other optical heads are generally similar (the same is true in the low-end recorder industry), so the main control chip plays the same role as the motherboard, which is very important or even more important. , of course, I believe that Pioneer optical drives are still of medium quality, and they are still passable. After all, they don’t have the reputation and reputation of Sony, but the price is too high. I think DIYers who are used to Pioneer can consider a change of taste (people who buy the machine generally Everyone is used to some kind of optical drive), and now Pioneer has no advantage. In the words of a certain boss, adding the name of Pioneer can still enter your field of vision. In addition, Pioneer has fully cooperated with ASUS starting from 123 (black DVD-123D, off-white 123A and silver 123E), so anyone who knows a little bit understands that ASUS products are completely Pioneer products (for complete reasons, please see the recorder Partially), but ASUS's optical drive has multiple silent functions (actually Pioneer's also has it, but it's not the one mainly promoted by Pioneer), so it's better to buy the ASUS one. Because they are all made by ASUS itself, ASUS also has a mute function. The most important thing is that ASUS's service is good, at least better than Pioneer. Generally speaking, those with backgrounds such as benq, LG, Samsung, and ASUS have good channels and services (relatively Yes, at least it's better than Sony, Pioneer, and NEC and the like, which are much better).

2.Sony’s optical drive has a very bad reputation in the mainland market. I’m not biased about this. Its DDU162X and 163X are completely BTC (a relatively weak optical drive OEM, and there are no classic ones. The product is made by LJ’s spokesperson). In addition to its good-looking appearance and the strong channel capabilities of the agent Qixi, the initial disk reading is very strong. Unfortunately, the typical lifespan is low. Recently, it was said that the king of disk reading that adapts to China’s national conditions is none other than XD , but the Sony 1615, which has been discontinued long ago, is good. It is manufactured by Lite-ON (Lite-ON). This is the quality of Sony. Of course, when I talk about Pioneer and Sony, I don’t mean that they don’t know how to make things. The main reason is that they are dissatisfied with the lower absolute profits. For example, Pioneer produces its own laser heads and is a major optical drive manufacturer (it has now been entrusted to Asus). , and its own baldness is very good, but it often doesn’t use its own things. Apparently it feels that its products are expensive and it’s not worth the loss to you. The things are good, but many people don’t know that they are good, so they can’t sell them and lose the market. The price is never Quality is a big enemy, especially in China, which is low-cost and low-tech. Pioneer has done this several times before, and each time it was criticized. The reason why 121 is so impressive to this day is because 120 is really too good. , just to reduce costs, it uses Taiwan's worst main control chip, which makes its disk reading, noise and heating all the worst. In order to save face, it came up with 121, using its own third-generation laser head and Panasonic's main control, all of which are It's a good thing, it's very popular, but the profit is very low, especially since the price of optical drives started to drop last year, so I took advantage of 121 and launched 123 to promote a shorter body. The main control chip is a cheaper MT than before, and I keep repeating it. , use high quality to attract you once, use low quality to make money next time, and the next time... However, the worst and weirdest Japanese optical drive is Sony, which jointly invented the optical disc and optical drive with Philips. Their optical head technology alone is very good, just look at high-end CD players. Unfortunately, Sony is only the most active in development and production. When I was young, I found an OEM (mainly charging royalties). In order to maximize profits and reduce costs, the measures taken were nothing more than sacrificing quality to grab the market. This approach is not surprising in China, and it uses backward products that cannot be sold. Sold to China, global quality control determines that the worst is sold to China (those who buy burnt discs must know this very well). This is even more true for Sony, which is trying to harm people by making a BTC product, but its domestic products are good products manufactured by LiteXing, XD.

3. Benq, in the field of opto-magnetics in mainland China, BenQ is a heavyweight, and its output is large. There are many OEM manufacturers. The quality is average, some are good and some are bad. It’s a mid-range product. It’s not a loss if you buy it. At least it supports domestic products (who say there are many angry youths in China). The new 1650v series has good disk reading capabilities and noise control. The lifespan is not bad so far. It’s much better than the previous ones. Stupid Ball ( Nickname) products are easy to buy, but the disadvantage is that many people in China who are not very mentally healthy prefer domestic products (that is, they look down on domestic products, worship foreign brands, and lose their temper easily). I think this is not objective and stupid. Optical storage has only been around for a few years, and it has made great progress. In the early days, its products were really not that good. At least I tried the crocodile and the like and I was very dissatisfied and dared not buy it. But recently, the quality of the products has become pretty good. In fact, everyone should go check it out. Just look at the world's CD-Rs. They used to be inconspicuous, but now they have almost unified the mid-range CD-R market. If you ask anyone, almost all of them are Benq 52X new platinum (except for music discs). It is also true that current DVD drives are generally relatively streamlined. In short, Benqiu's is not bad, the quality is at the same level as Pioneer/ASUS, and it is worth buying. Of course, it is not much better. The ALI M5721D main control chip is of ordinary quality. The price is there, so it is convenient to buy. By the way, it comes with a three-step attack on a stupid ball optical drive (not a recorder):

1. It is famous for its reputation. The quality of its optical drive has been analyzed before. It is just mainstream, with large output and little initial experience. The optical drive itself There are good and bad, individual differences are great, and they are often attacked.

2. Because it is made in China (although many top foreign brands are also made in China), the domestically produced Benqiu must be very poor. The Benqiu is not a famous brand, so once you buy Benqiu, If the ball is broken, he will be full of grievances, curse, and complain in tears, and criticize his body to pieces. On the other hand, if it is even very LJSony, it would be a guilty conscience to remain silent (Nissan must be good, and the occasional one may be an exception).

3. Wave after wave of criticism makes novices have no choice but to buy the "good reputation" Pioneer 123 or even Sony 1632, which is a waste of money.

4.Lite -On Lite, as an optical drive manufacturer in Taiwan (note that Lite is not the same as Yuanxing, which registered trademarks in mainland China), Lite has very good technical strength and is only popular in professional forums. Second to Plextor, generally speaking, anyone who knows a little bit about optical drives likes Lite. The price is cheap and the workmanship is good. Many major manufacturers use it as OEM. The reputation is very good and the products are reliable. Unfortunately, Lite The sales in mainland China have not kept up, and the praise is not popular. The advantages of Lianxing can be said to be above average in all aspects, especially the DVD format support performance is very good, the disk reading and service life are good, but the disk reading noise is loud , it’s a pity that the mainland doesn’t buy much, because many second-level cities can’t sell them, and the products in big cities are not all available. Specifically, at present, there are three models: gold and silver Fox 167T (panel color), and 16P9S series. The difference is not big. 107T has been discontinued due to high noise (others are good), but there are many sources of goods. In many places, they even only sell Golden Fox. The 16P9S is a newer model and has slightly lower noise. The other differences are not big. It would be better if there are some. Many well-known optical drives, such as Sony1615 and NEC5800, are of this model, and even the firmware can be flashed to each other. Since they are not as demanding on profit as Pioneer, the brand cannot afford to lose (just look at the poor stupid ball), experience The products are rich and of reliable quality, so they are very affordable. However, as I said before, you may not be able to buy genuine products from small places.

5. LG optical drive. Although LG is the world's largest optical storage company (HLDS-Hitachi LG Data Storage Alliance) and occupies a huge OEM market, its sales in mainland China are small. I feel that its optical drive is still Yes, it is famous for its durability and balance. The disadvantage is that LG's products are very good, and there are a few bad ones. Generally speaking, they are good. Many students are using the earlier LG 40X optical drive (CRD-8485B) very well now. 5 It's been years, but there is also a certain model of LG's CD burner (forgot the details) that will explode the disc. Overall it's worth recommending. Taking 8163B as an example, it is much better than 61 and 62. It has good disk reading ability, and like the discontinued Pioneer 121, it uses Panasonic chips. It may be one of the very few DVD drives that use mid-range main control chips. It is very 8163B. wrong.

6. BTC (Yingqun), MSI, Patriot, and Taipower are all from the same brand. I don’t recommend them. I heard that BTC is the “worst quality”. I also feel that the products manufactured by BTC are all of the same quality. LJ, it’s useless to hang on to Sony. You’d better not buy it. Although Jianji and others are under the same Acer umbrella as BenQ, they are inferior. Samsung’s General Jin (MT 1355PE+ SF-HD68V) has incomplete information (Herbalife is a big one). Heap) I heard it was just so so.

It’s enough to write so much about the optical drive. Now let’s talk about the recorder. The recorder is very different, and there are also technical differences, so the difference is very big. Moreover, the profit of the recorder is very high. How many majors are there? Each manufacturer has its own characteristics and is unambiguous. It seems that there is no need to save saliva.

There are not many manufacturers of recorders, and they are very complicated. The most important thing is that it is very easy to buy the wrong one, and there are many differences between different models. Let’s talk about the technical issues that are easy to mislead first. Many people buy recorders not for use, but purely for “technical” reasons.

First of all, let’s talk briefly about the history of DVD. In the early days, DVD was formed by ten companies: Hitachi, Panasonic, Mitsubishi, Philips, Pioneer, Sony, Thomson, Time Warner, Toshiba and JVC. Its current status It is the steering committee of the DVD Forum (this "forum" is just an industry organization, not a real online forum). Although several others later joined, they are the ones who can collect patent fees at the core. They developed DVD-ROM (that is, ordinary DVD discs). , not recording discs), they split internally after launching DVD-RAM. Sony and Philips still insisted on their beliefs and independently developed their own DVD burning specifications, thus joining forces with HP to create the opposing DVD Alliance. (also an organization), later joined by Mitsubishi Chemical/Verba, Ricoh, Yamaha, Dell, and Thomson. The main technical veterans are Sony/Philips, the old partners who jointly invented the CD. Many disc manufacturers have joined them. Their Invented DVD +R +RW +R DL. Currently, there are about 60 members of the DVD Alliance***. The original DVD forum now has more than 200 members, but the members are of little use and are just deceptive. The specific manufacturers are:

DVD-RAM was jointly developed by Panasonic, Hitachi and Toshiba. DVD-R/RW was developed by Pioneer Company of Japan, while +R/RW was developed by Philips. .

In terms of technology and market share of consumer recording disks, the DVD Forum is unfortunate. There is not much technical difference between +R and -R (+R is slightly more advanced because it is later), and the market share is seven to three ( +R is very popular), and it is basically the world of + on RW and DL. Thanks to the development of booktype, + has completely reversed the situation of poor support for + series optical drives. Booktype technology allows any disc of + to be recognized as DVD-rom is an ordinary DVD movie rather than a burnable disc. Therefore, unless the optical head of the DVD drive is old, all + burnable discs should be supported, such as DL (double-layer burnable disc). Due to its late launch, even -R DL has many of its own Even if the optical drive does not recognize it, +R DL has an absolute advantage, and the same is true for RW, and the fault tolerance of +RW can reach up to 512M, and the life and reliability of the disk are much better than the hastily launched -RW ( However, the recognition of RW is not bad, and only a few people use it), even higher than 100M of RAM. I am not judging the merits of + - here. When it comes to the ordinary + -R, price is actually the king. Whether the optical drive's shopping guide supports booktype is an essential item for detailed evaluation abroad. If your disc is only used for backup, regardless of whether it can be read on other machines, or does not involve RW or the like, only use DVD R (-R is supported by all, +R is only not supported by some older DVD drives), you don’t need to care about it; but if you want to consider compatibility, it means that it can be read on other people’s computers. , especially rewritable RW and double-layer DL, then booktype must be considered, because under normal circumstances, RW + RW is more expensive (the reason has been explained earlier). Specifically, booktypes are divided into three types: +R, +RW, and +R DL. Except for +R DL, the Japanese manufacturers under the DVD Forum generally do not support comprehensively. Of course, if you use unofficial cracked firmware, there will be an exception.

This also shows that whether or not booktype is supported is not a technical issue, but a matter of interests of DVD forum members. In this regard, Philips, Sony, and Taiwan (MTK) have much better support. Although those that do not currently support booktype can also burn +R/RW series , but if you consider the reading of other machines, be careful because many old DVD drives (which have a large number of domestic ones) cannot recognize it well, especially +RW and above.

By the way, although the recorder is not very mature yet, there is no problem with DVD +R and -R, but RW and DL are still making progress. However, more than 80 or 90% of players use +-R, and nearly 10% of users use RW. The remaining few use RAW, DL (by the way, DL is also called D9 recording disc) and the like. . DL may still have some promise, but RAM is really unnecessary and embellished. First of all, the advertising selling point is "removable optical disc". Since it can be moved, it can at least be read elsewhere. Unfortunately, most optical drives (even many of the optical drives currently available) basically do not support it (even if a few support it, the speed is very slow). ideal), move, and dream more realistically. Secondly, "10,000 erases and writes" is very tempting, but it is actually based on good protection and high-end workmanship. In fact, excellent RAM standards are packed in boxes like floppy disks. These alone are different from those that run naked. It's very big (think of a floppy disk running naked), and this is a theoretical value. In fact, low-end RAM disks are really average (including some Japanese disks) and cannot afford to be messed with. If there are many "error corrections" in China It hangs faster under the care of "King" and "Super Disk Reader" optical drives. Finally, due to the price factor, a high-end, decent RAM costing hundreds of dollars is not as cost-effective as a mobile hard drive. Of course, I would like to raise two points: 1. RAM is not used by no one. Many large companies use it for network dumps. Secondly, due to the advancement of current chips, many recorders have RAM functions themselves, so forget it. What I mean is that RAM does not matter. Whether or not it exists is not a factor worth considering. By analogy, if the new recorder is only better in DL RW than the old model, the chip has not changed much (just a step forward), and the price difference is more than 30 yuan, I think the decision will be easy. By the way, take the current situation as an example. Since DVD +R and -R have matured, 16X has basically been capped and will not be increased (except for PX). Therefore, in the future, only the speed of +RW and +R DL will really deserve the attention of a few people. , other RAM, -R DL are just fancy, it doesn't make much sense to be fully compatible. What does it matter if a disk that will never be used in a lifetime is not compatible?

I also want to talk about the place of origin. I often see people fighting over the place of production. In fact, Malaysian and even Japanese products are not necessarily very good. Making something always requires experience. Malaysian products are not necessarily better than us, especially in terms of equipment and employees, but our country’s products are not necessarily better than ours. Factories are generally installed in recent years, and experience is inevitably insufficient. However, Malaysia has more experience than us. Malaysia = old horse, ^_^. The quality of employees and management in Japan are indeed much better, and there are no technical barriers. Of course, it is quick to get started and relatively good, but unfortunately it is also expensive. Besides, the low-end recorders costing more than 400 yuan were transferred to Japan because they could not bear the cost. As for manipulation, there seems to be no evidence of this. Recently, my country's famous Benq has also gradually improved and accumulated experience. At least the improvement compared to 1620 and 1640 is obvious. Looking at the main controller and bald head alone, Lite is not necessarily very good (even lj), but it has rich experience, so it has a good reputation. Domestic production, by the way, it should be said that mainland production is mainly due to experience. I recently read an article about the origin of headphones and found that many Japanese and even Malaysian ones are actually made in mainland China. The appropriate foreign-friendly sentiment has been hit, ^ _^. According to international trade laws, the place of packaging is the place of production, so many cunning manufacturers have resorted to tricks. After production, they go abroad and then come back, purely for our sake (Nissan's Pioneer is an exception). Among the recorders, even the most high-end civilian ones such as PX712/716/755/760 are made in China (the design is Japanese), and there are even more OEMs in Taiwan (also considered domestic). It is really not very mature to look at the place of origin alone. , on the contrary, foreign forums are quite open to Made in China.

By the way, a slight correction is that some manufacturers have several factories corresponding to different sales regions. Generally speaking, the ones in Malaysia are similar to those in mainland China (don’t believe the nonsense about using Japanese original factory standards), but there are a few manufacturers that do. Those made in Japan seem to use better materials than those made in Malaysia (hearsay), and the standards are stricter than those made in China, but they are generally only sold to Europe and the United States, and may not be available in Taiwan.

Finally, let me talk about the optical drive reviews on websites and newspapers. I suggest that unless there are any major problems found in the reviews, it is best not to read them, or not to use them as an important reference. In fact, it is obvious that many people buy recorders. I always hope that it can be used smoothly. Of course I am satisfied with a better burned disk, but it should not be too bad. The most important thing about a recorder is its longevity. Many recorders cannot be used for a long time. And, to be honest, it’s hard to be convincing by using a few recording disks and making a recording curve to prove a good machine. Each recorder has its own discs that are suitable for it, and it also has its shortcomings. Different types of discs have different discs. Thousands of things, reviews can't reflect anything. For example, it's normal for a recorder that's only good at -R to record well on some +R discs. Even if the specific disc's ring code is changed, the difference may be much different. Moreover, most of the "fair" reviews have been done and are easy to manipulate. If anyone objects, in fact, the review of recorders receives a large proportion of benefits (advertisement feedback). It is too dangerous for a novice to read, and it is better to go to some optical drives. Check out the popularity in professional forums to get a practical idea (instead of being ripped off by stupid questions like which one is better for burning). The most important thing is that in fact, the recording curve of the optical drive is different due to different technologies and batches. The difference does not mean that it is poor in actual use. The most important thing for a recorder is its service life. This can only be proven by time and reputation. It has never been the case. I hope you will be good at reviewing reviews. If you are a novice, the more pertinent opinion is not to read it, so as not to be prejudged by dirty brands.

As a side note, I mentioned the issue of included items. As we all know, recorder manufacturers have a close relationship with disc manufacturers, and some even specifically collect royalties from disc manufacturers, so many recorders, especially new and old models, are on sale. I often give away things, and I am a bit stingy. I give away things like key rings, boxes, cups, etc. You can buy them in Yiwu for 1 yuan, which is boring. The most encountered ones are bundled discs, such as N pieces of Mitsubishi 16X DVD-Rs. That’s not bad. Mitsubishi’s current price is more than 3 yuan per piece, so you can just discount it. But be careful, some stores often discount, or some The manufacturer sells Weibo as Mitsubishi. Although Weibo is a second-tier manufacturer under Mitsubishi, the quality is not the same. Many of Weibo are even inferior to the Weiba Chameleon series that are manufactured with inferior disks due to contract reasons. To put it simply The price of Weibo is very average, and the quality is also average. Be careful when trading Weibo Donkey Cat for Prince; some of the discs given away are even worse, they are low-end Leide, MCC, and nature films, which are considered okay. . Some manufacturers even give away the aforementioned, of little significance, -R DL, RAM and the like. No one buys these disks. Due to pressure, the disk manufacturers will produce some and purely rely on the tie-in with the recorder to clear the inventory. (I guess the internal price must be very cheap). In a word, it is useless: it looks like the platter is worth some money, but for actual use, where can I use it? So I suggest you just ignore this kind of disc.

To add, today’s children are very naive. They always talk about Blu-ray (BD for short) and HD. They are coming soon. DVD has no meaning and has to be eliminated. In fact, the BD and HD camps are not like DVD. They started out They are completely opposite to each other. In theory, the cost of optical drives that support BD and HD is not low, so the integration of them takes time. The most important thing is that these things need to be popularized by the masses, at least for a long time, especially in the case of opposition. Even if they are released, it will take a long time for samples and popularization to the common people. If BD and HD cannot reach 8X, there will be no recording value at all. High-speed disks Film technology has too high hardware requirements, and today’s hard drives are very demanding (to put it simply, even if it becomes popular, the current low-end configurations are still very reluctant or have been eliminated long ago). Let’s look back at history. DVD will only be completely eliminated in the second half of this year. It has been unified. In the first half of the year, there were still "experts" recommending CD-ROMs at a price of around 4,000. VCD was released in 1989, and DVD was finalized in 1995. There have been changes in the world, and it takes at least 5-10 years for a product to mature. The popularity of BD and HD will not be fast. Now there are only ROMs. XD-R, XD-RW and speed improvements still have a long way to go.

By the way, my personal opinion is that although BD is bigger, HD is also big enough. HD discs are cheaper, and the encryption copyright is much better than BD. It may be more suitable for computers. Microsoft is also forced to take a stand, and there are some good things to watch.

I would like to state at the end that DVD recorders, especially in coastal areas, also have a lot of fake and repaired products entering the market. In addition, although recorders are better than optical drives, the quality is always uneven. There may be good brands, and there may be bad brands. For example, ASUS motherboards are inevitably broken, and there are many Colorful graphics cards that are very good, so don't be confused by individual phenomena. Furthermore, there are some additional things for DVD burners, such as 86 data cable, turning on DMA, power supply, learning to use nero, learning to open booktype, learning to burn files, music, and movies, refreshing the firmware, paying attention to the system burden when burning, and burning speed Issues such as whether it is safe, disc selection and identification, etc., are basically all the issues that come into contact in the initial stage, and they are not necessarily the cause of the recorder.

Let’s get to the point and start the detailed analysis. Since there are many models on the market, there are those with light engraving, SATA, external, etc., which are generally similar to the built-in ones, so I won’t analyze them (in fact, I understand these Not many), only representative styles are cited. In analysis, we only look at the ability to burn discs, because when you buy a recorder, you burn it first, and reading the disc is secondary. However, the current recorders are more or less slow to recognize the disc and select the disc. Who is called DVD? The forum and the alliance fought and launched a lot of DVD recording disc formats (note that even for RAM, there are many different specific standards, which is troublesome), and the people suffered. But generally speaking, there are two schools - -R and +R. If -R is good, +R is generally worse, and there are also +-R that are okay. It is difficult to say specifically. Are you saying that +R of a certain system is not good? Some discs are surprisingly good, so I'm just talking about them as a whole, which is basically objective. In addition, in terms of hardware, from the main control chip of low-end models, excluding high-end and rare SOC chips, if Renesas scores 90 points, then Philips and Panasonic score 80 points, and NEC and MTK score 70 points. As for the bald head, as mentioned before, although the bald head is almost as important as the main controller, the bald head is more homogeneous. For example, XBOX often changes its bald head, and Sanyo, which was acquired by NEC, is similar to Philips and Pioneer, but Samsung has A certain Taiwanese brand of bald hair is said to be inferior. Generally, many people like to discuss the main control of recorders (we won’t discuss the more specific and secondary motors), but what is most practical depends on the workmanship and performance. The main control and head are only part of the cost. Some people It is unkind to say that it accounts for 80%, because this is just a quotation. Who doesn’t have software “worth thousands of dollars” at home? Workmanship is more important, design is more important, service is more important, and lifespan is more important. Even with the same main control, the difference between good and bad is extremely obvious.

Now let’s get specific. First, let’s talk about the leader of recorders, Japan’s PLEXTOR, or PX for short. Its high-end recorders are super expensive, costing thousands is normal, and they are well-equipped. Saddle, Plextor chooses disks. The recording effect of those disks that cost around 2 yuan may not be as good as those from Samsung. The disk reading is also the D version, which is different on some models (such as 712), but the high-end disks are very good. . Plextor has comprehensive professional testing software and dedicated burning software, and almost all disc tests use Plextor's recorders as the standard. It is the only choice for wealthy but patriotic people. The only high-end product in China is PX. Can be considered. Having said all the good things, Plextor has recently been involved in the low-end, and has also released several models with affordable prices, such as 740A/750A. Many people criticized it and said that it was made by Benq. The implication is..., in fact, it has been the top model for a long time. The ultimate 712/716 is made by Benq. The difference is that 740/750 are OEM, while 716/760 and the like are completely independently developed. However, although Puckett is good, he is not alone in seeking defeat. Moreover, his successful entry into the Chinese market was also supported by a large number of high-level shooters in the early days on CD and other professional websites. Many of them are now veterans.

In terms of quality, Plextor's mid-to-high-end products are still very good, and they are one of the few independent manufacturers. Since the demise of Yamaha, the only competitors that can barely compete with them are Teac, which generally uses Sanyo's mid-to-high-end bald products. product, and it is a SoC designed with a single main control chip (such as 716A's LC897492). By the way, just like the habits of some Nissan main controllers (mainly due to the pettiness of DVD forum members), the top 712/716 adopts Sanyo's latest High-end chips (Sanyo has many kinds of chips, and SOC's are the exclusive and highest-end ones) do not support the +RW booktype (+R and +R DL are supported), so this is not a big problem. It is recommended that if you buy it, the platter should be Mitsubishi or Yuden grade. At the low end, he is a bit lazy and directly hires OEMs from better low-end products. For example, the 740 is designed by Philips and the 750 is designed by Teac, so it is more cost-effective to buy directly from the manufacturer.

There are also products from ASUS and Pioneer. First of all, to break the suspense, ASUS and Pioneer are integrated on DVD. Their cooperation is not simple. It is not an ordinary partnership like Sony and Lianxing. , Pioneer sold a complete set of technologies and even its own bald head to Asus (Pioneer is very satisfied with the royalties). It can be considered that Pioneer's things in China belong to Asus, and there is no need to consider who the design belongs to. They are allies in Southeast Asia. But what should be added is that they are not a complete alliance, because the products sold to Europe and the United States are manufactured by Japan's Pioneer factory instead of ASUS, which is somewhat different. Under the guidance of Pioneer, ASUS has been in the industry for a short period of time, but its quality and market share are good. Pioneer's optical drives in Southeast Asia are basically OEMed by ASUS. Due to cost constraints, the later stages and packaging are only made in China in China. There are also some rumors that Pioneer It would be unwise to help Asus manufacture products and Pioneer itself to produce them in mainland China (and don’t think about Asus itself being very big). The mainland ones are definitely ASUS, and countless teardown comparison pictures have shown that they are integrated. Some Pioneer circuit boards even have ASUS written on them, which shows that they are ordinary. Specifically, Pioneer 109 (corresponds to ASUS 1608P), Pioneer 110 (corresponds to ASUS 1608P2S), and ASUS 1608P2 (the rarer counterpart to Pioneer may be 110D, which is not common, and will definitely be 110 or above in the future). Now because the price of 110 is on the high side, and the main difference is the boring compatible RAM mentioned earlier, we might as well take 109 as an example, which is Pioneer's bald head and NEC's main control (D63641GM, 110 is D6364 5GM, but the main control origin is Japan, and the origin of the main controller used by NEC is China, which is strange), but the workmanship is not bad. It is a rare non-short body and weighs 1000g (maybe due to the silent material). It is very solid, has not shrunk, and feels solid. Awesome. Pioneer's position in the recorder retail market is pretty good. Many people come to Pioneer for roasting large amounts of chicken. It has a good reputation, especially in China (in fact, many people in China only know how to record recorders first
