A disk playback device with disk changer functions and having a stacker for storing two or more disks for playback allows a new disk to be added or disks to be changed without removing the stacker. The disk playback device is also convenient for playback of single disks not to be stored in the stacker. Transport of the disks is accomplished by displacement of holders in which the disks are individually received. When a disk is in the read position, it is clamped in place and the holder is lowered to a nonobstructing position to allow the disk to be read. The number of holders exceeds the number of stored disks, whereby a vacant holder is available for conveniently reading a disk not stored in the magazine.
