Title: CARTRIDGE HOUSING PROVIDED WITH A PROTRUSION TO PREVENT IMPROPER INSERTION
Abstract:
A cartridge for a disk drive has a rigid shell with a keying ear (22) and two keying grooves (24, 25). The keying ear is located on the rounded front at one corner between the top and bottom surfaces of the cartridge shell. The ear cooperates with a projection located in the drive along the drive receiving slot. The keying grooves are along the top and bottom edges of one side of the cartridge. These groves mate with projections on the cartridge receiving slot in the drive. One of the grooves extends deeper into one planar surface of the cartridge than the other groove. Both keys prevent insertion of the cartridge with any other orientation of the cartridge than the correct orientation.
