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 removable cartridge disk drive (100) includes a removable cartridge (20) adapted to be received by a disk drive (100) having a base plate (104) and right (102) and left (103) guide walls. The cartridge (20) inserts into the drive (100) at an angle by means of a movable slider (116) attached to one of the guide walls (102). Once inserted, the cartridge (20) is locked in and held. During operation, a rotary actuator arm (180) with adjustable angular orientation loads one or more read/write heads (182) off of a fixed ramp (176) onto the surface of a data storage disk (42) contained inside the cartridge (20). After read/write operations are finished, the head (182) is unloaded onto the fixed ramp (176) and the cartridge (20) is ejected from the drive (100) at an angle.

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 method for applying an optimal seeking technique to a disk file with excessive repeatable runout includes a method of modifying a control signal (ue(k)) provided by a controller (16) for controlling a rotary actuator arm (12) of a disk drive. The control signal (ue(k)) is modified during track seeking by adding a runout state (xa(k)) that is calculated each time a servo sector of a target data track on a surface of a disk is sampled by read/write heads carried by the actuator arm by a runout compensator (18). The modified control signal (up(k)) is provided to the actuator (12) for positioning the head to a desired track. A calibration algorithm can be used during track following to determine runout magnitude and runout phase at various preselected calibration tracks on the surface of the disk. A seeking algorithm can be implemented to compensate for the relative runout magnitude and phase variation between calibration and target tracks.

Abstract: A single mechanism is used to launch and retract the read-write heads from the medium of a disk drive. The mechanism includes a retraction lever (91), a retraction lever lock (118), a mechanical biasing member (76), a disk (37), and a voice coil motor (16). During launch of the read-write heads, the mechanical biasing member balances the emf generated by the voice coil motor. After launch, the voice coil motor is used to rotate a retraction lever and increase the potential energy in the mechanical biasing member. The retraction lever lock then is used to store this built-up potential energy. If the drive later experiences a loss of power, the mechanism automatically retracts the read-write heads from the media. During retraction of the read-write heads, the stored mechanical energy is applied to the retraction lever, which then automatically retracts the read-write heads.
