Abstract
A multiple-disk player which detects a time period during which for the player operates in the non-playback mode after the playback start command is issued and calculates a time period value on the basis of the difference between the current value of the time information datum read out of the disk and its preceding value; the detected non-playback mode time period is added to the playback time period to produce the total time period; and performs a fade-out operation for music being played back when such total time period reaches a given allowable time period. Consequently, it is possible to quickly and accurately check the fade-out operation even before all the pieces of music to be played back are actually played back.
