Sony received a design patent on a Compact Disk Player, originally filed in 1980.
The Minnesota Mining and Manufacturing Company (aka 3M) filed a 1962 US Patent application, issued as 3,381,086, in 1968, for a method of recording video and audio information on a rotating disk using an optical beam. This could be viewed as a direct precursor to the "compact disk" that was described in the literature for audio recordings shortly thereafter. The term "compact disk" is found in patents filed in 1980. There was apparently early debate over the merits of concentric tracks versus spiral tracking. So, there may be some other specific date upon which the modern standard was developed.
A:The compact disc or CD was introduced in the year 1982. It was originally developed for storing digital audio and digital data.
It all started in the year 1979, when Philips and Sony got together to design a new digital audio disc. The team leaders of this project were Kees Immink and Toshitada Doi. Philps handled the maunfacturing process along with the Eight-to-Fourteen Modulation (EFM), while Sony too care of the error connection method, better known as CIRC. However, Philips claim that this invention was not a one man's job but a collective contribution by members of both the companies who worked together as a team.
It was considered as a "Big Bang", in the digital audio world. This disc was taken over by nearly all markets across the globe, especially the Europe and the United States consumer market. The first successful CD to be launched was Brothers in Arms in 1985.A compact disk (CD) is a popular form of digital storage media used for computer files, pictures, and music. The plastic platter is read and written to by a laser in a CD drive. It comes in several varieties including CD-ROM, CD-R, and CD-RW.
James Russell invented the compact disk in 1965. James Russell was granted a total of 22 patents for various elements of his compact disk system. However, the compact disk did not become popular until it was mass manufactured by Philips in 1980.
The first working prototype was produced in 1979, and CD players were released in 1982
Sony introduced the world's first CD player, the CDP-101 on October 1st, 1982. It hit the market with a retail price of about $900 and featured the now familiar slide out tray loading mechanism for the first time.
Variations of the optical disk and compact disc started to appear in the late 1970s. The ones we are used to were launched in 1982.

Sony released the world's first CD Player called the CDP-101[1] in 1982 utilising a slide-out tray design for the CD. As it was easy to use and manufacture, most CD player tray designs had followed this style of tray ever since. However there have been some notable exceptions.
During the launch of the first prototype CD player 'Goronta'[2] by Sony at the Japanese Audio Fair in 1982, Sony showcased the vertical loading design of the CD player. Although the prototype's design was never really put into actual production, it was for a time adopted for production by a number of early Japanese CD player manufacturers including Alpine/Luxman, Matsushita under the Technics brand, Kenwood and Toshiba/Aurex. For the early vertical loading players, Alpine sourced their AD-7100 player designs for Luxman[3], Kenwood and Toshiba (using their Aurex brand). Kenwood added their 'Sigma Drive' outputs to this design as a modification. A picture of this early design can be seen on the Panasonic website.[4]
== == Sony Discman D-50
As CDs overtook cassette tapes in both sound quality and popularity, Sony saw the need to update its popular Walkman line for a new generation. In 1984, on the one year anniversary of the introduction of compact discs, Sony introduced their D-50 portable CD player, the first ever portable digital music player.
