ABSTRACT:
An automatic disk changer in which a tray guide for storing a disk while it is not being played is provided in a case. A tray for containing the disk is guided by the tray guide. The tray has nearly the same size as the disk to be contained in the tray, and has a window through which a laser beam from a pickup passes and which extends to the peripheral portion of the tray. The disk changer includes a disk player which is also provided with a further tray guide for guiding the tray and is installed so that the disk is pinched and moved up by a turntable unit and a clamper and the tray is thereafter moved in the direction of movement of the pickup.
