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.

Abstract: A zone servo sector format alignment scheme (41) for a disc (22) of a disc drive (20) includes the disc (22) having an outer zone (42), a middle zone (44) and an inner zone (46), each zone having a plurality of tracks (48, 50, 52). The sectors (54, 56, 58) of each zone (42, 44, 46) include a plurality of sectors such as sector (60) which define a servo field (62) and a data field (64). The number of sectors (56) in each of tracks (50) of the middle zone (46) is less than the number of sectors (54) on each track (48) of the outer zone (42). The number of sectors (58) on each track (52) of the inner zone (46) is less than the number of sectors (56) on each track (50) of the middle zone (46). Further, by maintaining the same recording frequency of the servo fields (62) across all the zones (42, 44, 46), the placing of the sectors (56, 58) in the middle and inner zones (44, 46) can be adjusted in order to provide for alignment indicia (66) which include aligned sectors across all the zones. Such alignment indicia (66) are positioned about the disc (22) and facilitate the operation of the servo control circuit (36) for facilitating head seeking.

Abstract: A higher-capacity disk drive system and a higher-capacity removable disk cartridge adapted for downward compatibility with older, lower-capacity disk drive systems, wherein a unique control information format is stored on higher-capacity removable disk cartridges to distinguish them from older, lower-capacity removable disk cartridges and thereby to facilitate cartridge capacity recognition by the higher-capacity disk drive system. Upon recognizing the capacity of an inserted removable disk cartridge, the higher-capacity disk drive system can read and write data to the removable disk cartridge such that data which it stores on a lower-capacity removable disk cartridge may be read by lower-capacity disk drive systems.

Abstract: A disk drive employing a voice coil actuator to position a read/write head over a magnetic disk retracts the read/write head from the magnetic disk surface and passes an audio frequency alternating current through the voice coil to produce a corresponding movement in the read/write head support structure which generates an audible tone indicating the disk drive status. The alternating current waveform has a positive phase and a negative phase, with the read/write head moving toward the disk in response to one phase of the current and the read/write head moving away from the disk in response to the other phase. Audible tones of different frequencies are produced by varying the frequency of the alternating current waveform. In this fashion the disk drive generates a predetermined sequence of tones separated by silent pauses which identifies a particular disk drive status condition.
