    摘要： Certain example embodiments described herein relate to a micro-actuator for use with an HGA and/or disk drive device. A substantially U-shaped frame may include a cavity capable of receiving a slider. The frame may include two segmented, flexible side arms and a bottom support arm at least partially defining the cavity. Each segmented side arm may have a PZT element mounted on an outer surface thereof facing away from the cavity, and each may include a lower portion proximate to the bottom support arm and an upper portion disposed at an end opposing the bottom support arm. The lower portion and the upper portion may be at least partially separated by a gap. Accordingly, micro-actuators having better resonance and servo performance, reduced difficulties associated with the slider/micro-actuator mounting process, and/or better shock performance may be provided.

    摘要： Disk drives, methods, and computer program products are provided for controlling seeking of a transducer that is adjacent to a rotatable data storage disk in a disk drive. The disk drive includes a secondary actuator for positioning the transducer over a second range of movement, and a primary actuator for positioning the secondary actuator over a first range of movement that is larger than the second range of movement. The secondary actuator is controlled to move the transducer toward a target track on the disk while seeking. The primary actuator is controlled to move the secondary actuator toward the target track while simultaneously controlling the secondary actuator to maintain the transducer on the target track.

    摘要： A suspension for a HGA includes a suspension flexure and an out trigger. The suspension flexure has a tongue region having a first flexure part in a tip portion thereof for mounting a trailing edge of a slider and a PZT mounting region for mounting PZT elements. One end of the out trigger is connected to the suspension flexure, and the other end of the out trigger has a trigger support portion which extends above the tongue region so as to support the leading edge of the slider. The structure of the out trigger is capable of stiffening the tongue region of the suspension flexure and, in turns, avoiding the deformation problem and the dimple separation problem during the manufacturing process or in vibration or shock events. The invention also discloses a HGA with the suspension, manufacturing methods of the HGA and a disk drive unit having such HGA.

    摘要： A disk drive detects head touchdown based on a magnitude of a position error signal at a discrete frequency. The discrete frequency is one-half the disk rotation frequency or an integral multiple of the disk rotation frequency. The head is heated by turning on a heater at the discrete frequency, thereby injecting bias into a servo system that increases the PES magnitude. In addition, the servo system has a first transfer function for tracking the head during read and write operations and a second transfer function for tracking the head during head touchdown detection. The second transfer function has smaller vibration rejection than the first transfer function so that the disk drive is less sensitive to vibration during read and write operations than during head touchdown detection.

    摘要： Methods of compensating for repeatable runout in a disk drive are provided. The disk drive includes a data storage disk, a transducer adjacent to the disk, a primary actuator for positioning the transducer over a first range of movement, and a secondary actuator for positioning the transducer over a second range of movement that is less than the first range of movement. Estimates are made of the position of the secondary actuator in the second range of movement. Data is read from the disk via the transducer. A position error signal is determined based on the read data. Positioning of the transducer by the primary actuator is controlled based on the estimated position of the secondary actuator in the second range of movement and based on the position error signal to compensate for repeatable runout.

    摘要： A method and apparatus for determining embedded runout correction values when self-servo writing or partial self-servo writing is disclosed. In one embodiment, a disk surface, which has servo information written thereon, is provided. The servo information is grouped into 1x servo sectors and 2x servo sectors, and the 1x servo sectors and the 2x servo sectors form a plurality of tracks. A read head servos on the 1x servo sectors associated with a track. Both position error signals due to repeatable runout for the 1x servo sectors and information related to position error signals due to repeatable runout for the 2x servo sectors are determined, while servoing on the 1x servo sectors. Embedded runout correction values for the 1x servo sectors and the 2x servo sectors are calculated.

    摘要： In some embodiments, a functional object-oriented network (FOON) is provided that includes a plurality of functional units each comprising two or more input object nodes that each identify an object and its state before a manipulation motion is performed, a motion node that identifies a manipulation motion that can be performed using the objects, and one or more output object nodes that each identify an object and its state after the manipulation motion has been performed using the objects. In some embodiment, a robot can used the FOON to determine the discrete actions that are required to perform a given task.
