Abstract
A disk drive (30) conforms to the 1.8 inch form factor through of use of, for example, a removable cartridge (200) which has a disk (220) mounted on the hub (226) which hub (226) is manipulatable by a multifunction handle (58) of the disk drive (30), allowing the hub (226) to be seated on the spindle motor nose (56) of the disk drive (30). The multifunction handle (58) of the drive (30) provides for a compact, high capacity design by performing cartridge hub seating operations, cartridge ejection operations, head arm assembly unlocking operations, and handle locking and unlocking operations to ensure proper operation of the disk drive (30). The disk drive (30) includes an inventive ramp (66) design which allows the head arm assembly (64) to be initially received within the cartridge (200) as the cartridge (200) is inserted into its final registration position in the disk drive receiving mechanism (53) and to be more tangent with respect to the disk (220).
