ABSTRACT:
In a multi-disk player, disks such as compact disks and video disks are positioned on at least two tray mechanisms so that the signal reproducing surfaces of the disks on the respective tray mechanisms face in predetermined directions. Drive units are provided for each of the tray mechanisms, and each drive unit moves its the respective tray mechanism between a disk playback position and a disk ejecting position. A disk is clamped selectively from the tray mechanism which is at the disk playback position. An optical pickup device traverses the signal reproducing surface of the disk thus clamped to playback the data recorded on the surface of the clamped disk. Thus, a compact disk can be played back without removing a video disk situated in the disk player, and vice versa. Additionally, a video disk can be loaded and positioned in the disk player while playing back a compact disk, and vice versa.
