30 Years of CD






In 2012 it was the celebration of 30 years of Compact disc.

The Compact Disc was co-develloped by PHILIPS and SONY. As a result it was decided that the Compact Disc will have a diameter of 120 mm for a 74 minutes audio recording.
This is how it was presented in the "Red Book". The format was later adapted for storage of data (CD-ROM), write-once audio and data storage (CD-R), rewritable media (CD-RW) and other photo and video formats. Another format was the Mini CD, an 80 mm diameter disc.

This successful format was the basis for the DVD, a new audio-video disc with 120 mm diameter developed by PHILIPS, SONY, TOSHIBA and PANASONIC in 1995.

A higher fidelity format was in 1999 introduced by PHILIPS and SONY and it was called Super Audio CD a new audio disc in a format war with DVD-Audio.
