ABSTRACT:
A changer-equipped player uses an n number of carriages which can hold up to an n number of discs in storage positions in a stocker. These carriages carry discs between the stocker and a movable tray for play and for loading and unloading. One of the n number of carriages, carriage S, is usable in a single-play mode, allowing the player to be used as a tray equipped single-play device. Carriage S may be selected for single-play regardless of the number of discs stored in the remaining n-1 number of carriages. The remaining n-1 number of carriages are usable only in changer-play operation. Loading discs into the device is accomplished by placing discs into empty carriages as each is held in the tray in an eject position. The stocker is not removed for loading discs or for removing or replacing the discs stored within it. During changer-playback operation, the device selects and plays all stored discs in a predetermined sequence. During single-play operation, the device plays only the disc in carriage S.
