On This Day in Tech: October 1, 1982
On October 1, 1982, Sony placed the CDP-101 on sale in Japan, introducing the first commercially available compact disc player. The black, front-loading component arrived with a price of 168,000 yen and a catalog of fifty CBS/Sony titles. Consumers could now hear music stored as digital data on a reflective twelve-centimeter disc rather than as grooves on vinyl or magnetic patterns on tape. The launch did not instantly replace those familiar formats, but it gave the public its first practical look at an optical system that promised quiet playback, precise track selection, and resistance to the gradual wear caused by a stylus.
The machine was the visible result of a long engineering partnership. Philips had developed optical-disc techniques, while Sony brought extensive digital-audio expertise. The companies agreed on important elements of what became the Compact Disc Digital Audio standard, including sixteen-bit sampling, a 44.1-kilohertz rate, and a twelve-centimeter disc with roughly seventy-five minutes of playing time. Reaching the market was still difficult. Sony’s team had to improve the laser pickup, lenses, semiconductors, control circuits, and manufacturing process. A compact prototype appeared in 1981, yet more than two hundred technical problems reportedly remained before the commercial deadline.
Hardware alone could not establish a music format, so Sony also built the production chain around it. CBS/Sony prepared a cleanroom-equipped disc factory in Shizuoka, where manufacturing began only weeks before the launch. Releasing fifty albums alongside the player gave early buyers something to hear immediately and demonstrated that the system could carry classical, jazz, rock, pop, and Japanese music. The CDP-101 used a motorized tray, digital time display, remote control, and near-instant access to individual tracks. Those conveniences made digital audio feel different from simply improving the sound quality of a turntable or cassette deck.
Compact discs spread gradually because players and albums were initially expensive, and early adopters were often serious audio enthusiasts. Wider international releases followed in 1983, prices declined, catalogs expanded, and portable players soon brought the format beyond the living room. The same basic optical-disc principles later supported computer CD-ROMs and helped prepare consumers for DVDs and other laser-read media. Streaming eventually displaced the CD as the dominant way to obtain music, but the October 1982 debut remains a crucial boundary in consumer electronics: digital audio moved from laboratory demonstrations and engineering agreements into an ordinary product people could buy and use at home. That shared foundation also gave record companies confidence to invest in digital catalogs.
Philips contributed optical-disc research while Sony advanced digital-audio processing. Their cooperation produced a common twelve-centimeter, sixteen-bit format instead of competing incompatible systems.
On October 1, 1982, Sony launched the CDP-101 in Japan for 168,000 yen. Fifty CBS/Sony compact disc titles accompanied the player, creating both hardware and a usable music catalog.
The player offered quiet digital reproduction, a motorized tray, remote control, and direct track access. Those features made the new medium visibly different from vinyl and tape.
Producing the launch required reliable lasers, lenses, semiconductors, control electronics, and newly manufactured discs. Sony's engineers resolved hundreds of problems while CBS/Sony prepared a specialized disc factory.
International releases and falling prices turned the compact disc into a mass-market music format. Portable players and expanding catalogs helped digital audio enter everyday life.
The CD also familiarized consumers and manufacturers with laser-read media. Its optical storage principles later supported CD-ROM, DVD, and other digital disc formats.
