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： An actuator arm assembly has an actuator arm and an actuator for moving the actuator arm whereby the arm assembly experiences vibrations. The actuator has a body with a recess formed therein, and a strain sensor is fitted essentially inside the recess such that the sensor generates signals correlated to the vibrations. This arrangement produces a high gain boost from the strain based sensor, making an amplifier circuit unnecessary. The sensor signals are used to damp the vibrations.

摘要： A servo system for displacing a head relative to a disk of a hard disk drive. The servo system comprises a dual-stage actuator, a calibration signal generator, and a calibration factor generator. The calibration signal generator generates a calibration signal having a calibration portion. The calibration factor generator generates a calibration factor. The servo system operates in operating and calibration servo modes. In the operating mode, the system defines first and second servo loops. The calibration factor is used as one of the parameters of the second servo loop. In the calibration servo mode, the calibration signal forms the second control signal, and the calibration factor generator generates the calibration factor based on movement of the head before any substantial response of the third servo loop to the calibration portion.
