    摘要: RRO corrector function is formulated to partition the contribution of micro-actuator control from the other voice coil assembly contributions. Single stage actuation is supported by zeroing the micro-actuator control queue, otherwise multi-stage actuation is supported. The multi-stage actuation may include dual stage actuation and in some embodiments triple stage actuation. Triple stage further partitions RRO corrector function for the contribution of the second micro-actuator. Method of initializing an assembled hard disk drive creates hard disk drive as product, using the written-in parameter list for track on the disk surface to recreate the RRO corrector as RRO corrector filter using queues updated by NRRO corrector.

    摘要: A air bearing slider that flies above a surface of a recording disk during relative rotation of the recording disk. A plurality of projections extend along the side of the slider body, and a plurality of negative pressure air cavities are formed between the projections. The projections act as pneumatic bearings, creating supporting positive forces for supporting the slider. The negative pressure air cavities create negative forces for pulling the slider down. The positive and negative forces on the center of mass of the slider are balanced to provide a more stable, static, and dynamic flying attitude for the slider. The resulting pressure profile of the slider has high pressure near the leading end, relatively low pressure in the middle, and relatively high pressure near the trailing end. This ensures that the minimum spacing between the slider of the disk is very insensitive to roll parameters.

    摘要: A magnetic head follows a track in a hard disk drive as positioned by micro-actuator and voice coil motor. Embodiments operate two control paths. The micro-actuator control path generates a version of micro-actuator control signal stimulating the micro-actuator. The voice coil motor control path generates a version of voice coil control signal, amplified based upon tuning gain to stimulate voice coil motor. A decoupling feedback filter decouples these control paths, using the micro-actuator control signal version. Either control path may include a notch filter. A track following command, with PES removed, directs the micro-actuator control. The servo-controller may digitally support the invention, which may include the servo-controller program system. An implementation may be optimized within a hard disk drive, possibly as part of the manufacturing process. The hard disk drive is a product of that process.
