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), 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).

Abstract: A disc drive (20) including a spindle motor assembly (42) having a magnetic clutch plate (46) and an actuator (47) receives a hermetically sealed cartridge (22) containing a plurality of discs (72, 74) with associated heads (80, 81) mounted in the cartridge (22). Associated with an arm assembly (84) which supports heads (80, 81) is a component (50) for use with the actuator (47). With the cartridge (22) inserted in the drive (20), the actuator (47) operates to cause the heads (80, 81) to traverse relative to the disc (72, 74) as the spindle motor assembly (42) uses a magnetic field to engage a magnetic plate (77) associated with cartridge (22) in order to spin the disc (72, 74). Data transfer connectors (52, 54) are associated with both the drive (20) and the cartridge (22) in order to allow for the transfer of data between the cartridge (22) and the drive (20).

Abstract: A magnetic latch for latching read/write heads on a moving ramp in a removable cartridge disk drive system includes a latch mechanism and a latch plate (318), at least one of which includes a magnetically-attractive plate. The latch mechanism is attached to a voice coil motor actuator and read/write head assembly (302). The magnetic attraction between the latch plate (318) and latch assembly (316) retains the read/write head (308) on the ramp (304) in the presence of shocks and vibration to the disk drive. An associated servo control algorithm (900) controls the read/write head velocity while the head (308) is loaded on a magnetic disk.

Abstract: A disk drive (50) for receiving a removable cartridge (52) containing a disk (256) for storing data. The disk drive (50) includes a spindle motor (102) for engaging and causing the disk (256) of the cartridge (52) to spin at an appropriate speed and a mechanism (168) for mounting the spindle motor (102) to the disk drive (50) so that the spindle (102) motor is movable from a first position out of engagement with the disk (256) to a second position operably engaged with the disk (256). The disk drive further includes an ejecting mechanism (106) for engaging and lockingly holding the cartridge (52) in place in the cartridge receiver (60) and for ejecting the cartridge from the cartridge receiver (60). Further interlocking device (100) is provided for ensuring that the cartridge (52) cannot be removed from the receiver (60) when the spindle motor (102) is engaged with the disk (256) and for ensuring that the drive (50) cannot be enabled if the cartridge (52) is not received in the receiver (60). Removable cartridge (52) groove (332) for accurately positioning the cartridge (52) in a cartridge receiver (60) of the disk drive (50).

Abstract: PROBLEM TO BE SOLVED: To minimize clash between a read/write head and a recordign medium, and thereby to improve the reliability of a disk drive by employing one mechanism for launching/retraction of the read/write head. SOLUTION: The mechanism includes a retract lever 81, a retract lever lock 118, a mechanical biasing member (spring 76 or the like), and a voice coil motor 16. After launching, the voice coil motor 16 is used to rotate the retract lever 91 to increase the potential energy of the biasing member. Then the retract lever lock 118 is used to store the built-up potential energy. On the occurrence of a power failure of the disk drive, the mechanism retracts the read/write heads 55, 58 automatically from the medium. The stored mechanical energy during the retract motion of the read/write heads 55, 58 acts on the retract lever 91 to allow the read/write heads 55, 58 automatically to be retracted from the medium.
