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.
In 1962, Philips invented the Compact Cassette medium for audio storage, introducing it in Europe on 30 August 1963 (at the Berlin Radio Show), and in the United States (under the Norelco brand) in November 1964, with the trademark name Compact Cassette.
