摘要

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.
