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.


The compact disc or CD was introduced in the year 1982. It was

originally developed for storing digital audio and digital


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
