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.
CD ROMs, which are computer disk drives for computers, were first made in the year 1985. Writable or recordable CDs came later, in 1988. These, with the help of CD recording devices, let users make their own CDs, which they could then play on CD players. On a not so promising note, CD players are fast losing out on popularity, thanks to new digital innovations like the MP3 player.
