Audio compact discs, which feature uncompressed digital audio files, take up more space than compressed audio files like the popular MP3 format. There is a maximum of 74 minutes of music on an audio CD. As a general rule, one minute of a compressed audio file is approximately equal to 1 megabyte of data. Thus, a 700-megabyte CD can hold close to 700 minutes of compressed music files.
