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 CD produced was The Visitors by Abba. Piet Kramer, who was a member of the optical group at Philips during the disc's development, said: When Philips teamed up with Sony to develop the CD, our first target was to win over the world for the CD. We did this by collaborating openly to agree on a new standard.
