Sony released this technology in OCT 1982 as documented in this article. A few years later, this showed up in computer technology to be later replaced with DVD drives.
QUOTE: The digital music revolution officially hit 30 years ago, on Oct. 1, 1982. While you may be surprised to learn that the heralds of the coming age were, in fact, the Bee Gees, it probably comes as less of a shock to learn that Sony was at the very heart of it. After years of research and an intense period of collaboration with Philips, Sony shipped the world’s first CD player, the CDP-101. Music — and how we listen to it — would never be the same.
