ABSTRACT:
A disk player has a magazine for holding disks and mechanisms for transporting disks between four positions, an eject position, a load position, a playback position, and a store position. A disk reader is positioned to read a selected disk in the playback position while the selected disk overlaps disks in the magazine. The disks are held on carriages in the magazine and are transported on the carriages to the disk reader. Each carriage has a V-shaped aperture which provides for access by the disk reader to a recording surface of the selected disk. Clearance for playing the selected disk is also provided by the V-shaped apertures of adjacent carriages in the magazine. The selected disk is raised by the disk reader into an area within the V-shaped aperture of the carriage in the magazine which is above the disk being played. A selected carriage is carried by a tray between the eject position and the load position. The selected carriage is partially removed from the tray during transport from the load position to the playback position. The partial removal elongates an access aperture for the disk reader and allows a shortened tray length to be achieved. The tray has protrusions which extend into the V-shaped aperture and provide supplemental support for a disk held in the selected carriage. Countersunk apertures extend into the protrusions to facilitate removal of a disk from the tray and carriage.
