Hortens, a Dutch engineer who invented the cassette tape, died at the age of 94. As the head of the product development department of Philips, Hortens led a team to develop the original portable tape recorder; Then they launched the first tape at the Berlin Electronics Show. Their slogan at that time was:? Smaller than a pack of cigarettes! ?

? This portable tape quickly replaced the tedious reel recording method for a long time, and the tape brought music to the public. This is Hortens's goal: he decided early on that he wanted a music memory that could be put in his coat pocket, and even made a wooden model to determine the exact size. Ottens later told Dutch News:? I'm tired of those heavy and difficult music players. ? It's that simple. ?

cassette tapes? Be registered as a trademark. After reaching an agreement with Sony, Otis' design finally became the global standard of magnetic tape. Since then, more than 1 million discs have been sold. Later, Otis also led the team to develop CDs at Philips, with sales reaching billions. Until he retired, he attributed the credit of this music revolution to the people around him. ? We are all little boys and have a good time. He once said,? We don't feel that we are doing anything important. This is a sport. ?

? When I was a child, I lived in the countryside. When tapes and CDs spread, they would probably be eliminated in big cities. However, this still can't stop the happiness brought by tapes and CDs. I learn English through tapes. Now my English is still a tape cavity? The happiness brought by CD is immeasurable. On one occasion, several junior high school female students made an appointment to go to a lesbian scientist to watch a film. Her family was in town and the family conditions were good. The film I watched was a little embarrassing. What was even more embarrassing was that her brother-in-law came back in the middle? A room full of little girls, embarrassed, looked at each other, then laughed in a low voice and fled. Science and technology enrich and improve our quality of life, and thank those who have contributed to it.
