A compact disk or CD is a popular form of digital storage media used for âcomputer files, pictures and music. The plastic platter is read and written to using 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. 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.
