Abstract

A removable cartridge (200) for a disk drive (30) which has a 1.8 inch form factor, has multifunction features which allow for high data storage capacity at a reduced size. The cartridge (200) includes a cartridge screw (206) which engages the cartridge nut (221) defined in the cartridge housing base (204) for allowing the disk (220) in the cartridge (200) to be positioned relative to the cartridge housing base (204) in order to successfully engage the spindle motor nose (56) of a disk drive (30). The cartridge screw (206) additionally prevents the disk (220) from rattling within the cartridge (200) whether the cartridge (200) is removed from the disk drive (30). The cartridge (200) further includes a multiplicity of projections (212), (214), (214), tang (208) and rails (216) which contact the drive (30) to perform the functions of proper reception and registration of the cartridge (200) in the cartridge receiving mechanism (53) of the disk drive (30) and proper operation of the cartridge (200) as the cartridge (200) is manipulated by the disk drive (30).
