CD Digital Audio (CD-DA)

Phillips and Sony developed this so-called 'red book' standard in 1980. This was the original CD format for storing music digitally on a CD.

Audio data is stored in blocks holding 2,352 bytes of data with some extra bytes for error detection and correction. 75 blocks are required for each second of playback.

Therefore a standard 74 minutes CD will hold about 747MB of data.
