Beethoven’s Legacy Beyond Music: How the Maestro Defined CD Standards

  When it comes to setting standards, Beethoven is not the first person in the history of music, but he is the first person in the history of recordings. how do I say this?
  Many people don’t know that the length of CDs around the world is 74 minutes and 42 seconds. Even if you know, you probably don’t know why.
  The story begins in the spring of 1976, when the Sony R&D team showed Norio Ohga, the company’s top executive, a laser disc that could hold 13 hours and 20 minutes of music. This is the world’s first digital audio record. However, the record is over 30 centimeters in diameter.
  At the same time, the Dutch company Philips was also improving their laser discs. Three years later, Philips launched the first-generation laser disc, which was only 11.5 cm in diameter and could record music for one hour. The two companies decided to jointly submit record specifications to the International Digital Audio Disc Association (DAD), with a recommended length of 60 minutes. By this time Norio Ohga had been promoted to President of Sony Music Entertainment Co., Ltd.
  Norio Ohga is not a technical person. He studied at the Tokyo University of Arts and Music, the Munich Conservatory of Music and the Berlin State University of Arts. He was a professional baritone singer before joining Sony. He insisted that the CD should be 75 minutes long because: “A record that cannot contain Beethoven’s Ninth Symphony is incomplete!”
  Finally, the diameter of the CDs around the world is 12 centimeters, and the playing time is 74 minutes and 42 seconds, which can accommodate Beethoven’s “Ninth Symphony”.
  Fourth-rate companies sell hard work, third-rate companies sell products, second-rate companies sell brands, and first-rate companies sell standards. 152 years after his death, Beethoven set the world standard for compact discs never seen in his lifetime. Therefore, he is not the first person to set music standards in the history of music, but he is the first among all these “firsts”.
