Who Invented Compact Discs?

A joint task force by Sony and Philips Consumer Electronics are given the credit for developing the compact disk 1981 because they were the first companies to help the format gain popularity after Philips began manufacturing the discs on a commercial basis. However, the technology of reading a plastic disc containing digital data with a laser was developed by James Russell in 1965, fifteen years earlier. Russell received more than twenty patents for his work on the compact disk, but due to Sony and Philips’ ability to market the technology, they are given the credit.
