Abstract
A method and apparatus for playing compressed audio compact discs in a CD player is provided in which compressed audio data is cached in the local memory of the CD player. If a sufficient amount of compressed audio data is cached in the local memory of the CD player, the CD player can be placed in a reduced power state, reducing the consumption of power by the loader of the CD player. The determination of whether a sufficient amount of compressed audio data is present in the local memory of the CD player is made on the basis of a comparison of the playback time of the unaccessed cached audio and the restart time of the CD player.
