    摘要: A rotating media storage device (RMSD) that adaptively modifies pre-read operations is disclosed. The RMSD schedules a pre-read data segment on a second track of disk, commands a movable head to seek to the second track, and if an on-track condition is not met for the scheduled pre-read data segment, modifies the pre-read operation. In one example, modifying the pre-read operation includes canceling the pre-read operation and then performing a read data operation.

    摘要: A disk drive is disclosed comprising a disk having a plurality of data tracks, wherein each data track comprises a plurality of data sectors, and a head is actuated over the disk. A suspect sector list (SSL) stores a plurality of SSL entries, wherein each SSL entry identifies at least one suspect data sector. The disk drive further comprises a disk controller for executing an access command received from a host computer to access at least one of the data sectors. If an error is detected while executing the access command, the disk controller generates an SSL entry having a priority level selected from at least three priority levels and adds the SSL entry to the SSL. A verification operation is executed for each suspect data sector identified by each SSL entry, wherein the SSL entries are processed relative to the priority level assigned to each SSL entry.

    摘要: Disclosed is a disk drive using an accelerometer to sense linear vibration and cancel its effects with an adaptive algorithm during track following. The accelerometer is oriented to detect acceleration associated with torque that tends to cause the actuator to move off-track notwithstanding the efforts of the servo control system. The accelerometer's filtered output is used to modify the control effort. The disk drive uses the position error signal to adaptively filter the accelerometer's output in an effort to mathematically converge on a set of optimal filter coefficients and thereby reduce the effect of vibration that may otherwise impose a torque on the actuator.

    摘要: A rotating media storage device (RMSD) includes a disk having at least one track with a plurality of servo wedges, a moveable head, and a microprocessor. The microprocessor receives a plurality of position error signal (PES) values during track following and sums PES values for a plurality of different sets of servo wedges of the track to generate a plurality of shifted summed position error signal (SSPES) values. The microprocessor shifts the plurality of generated SSPES values by a phase shift value to generate a plurality of corrected shifted summed position error signal (CSSPES) values, which correspond to the repeatable runout (RRO) of the disk.

    摘要: A method of expanding the on-track operational range of a disk drive based upon detection of an external vibration condition. The method involves detecting that a vibration state exists and, while the existence of the vibration state is detected, modifying the default on-track-declaration algorithm such that a data transfer operation can be completed in less time than if the default on-track-declaration algorithm was in use.
