摘要： A bidirectional electrostatic rotary microactuator has two sets of fixed electrodes, one set for driving the microactuator counterclockwise and the other set for driving it clockwise, and a rotatable frame that has movable electrodes attached to its outer wall and interleaved between the fixed electrodes. A layer of insulating material is located between the outer wall to which the movable electrodes are attached and the remainder of the frame so that the movable electrodes are electrically isolated. The frame is maintained at ground electrical potential and the movable electrodes at a fixed non-zero electrical potential. The microactuator is driven by applying a plus or minus voltage to one set of fixed electrodes and the opposite voltage to the other set, while maintaining the movable electrodes at a fixed non-zero voltage. The microactuator is usable as a secondary actuator in a disk drive for fine positioning the read/write head.

摘要： An airflow shroud for either a moving-slider-type or a moving-head-type microactuator of a disk drive reduces off-track motion of a read/write element for either a moving-slider-type microactuator or a moving-head-type microactuator. One configuration of the airflow shroud includes a frame portion and an attachment portion. The frame portion has an opening suitable for exposing an air bearing surface of a slider for a disk drive and surrounds the slider and a moving-slider-type microactuator coupled to the slider. The attachment portion is adapted for attachment to a suspension of a disk drive. Another configuration includes a plate portion and a recessed portion. The plate portion is attachable to a slider having a moving-head-type microactuator. The recessed portion corresponds to the moving-head-type microactuator of the slider.

摘要： The invention is a moving-slider rotary piezoelectric microactuator as the secondary actuator for a dual-stage actuator disk drive. The microactuator has a substrate attached to the disk drive suspension and a rotatable frame that supports the slider, so the head-suspension assembly includes the suspension, the microactuator and the slider with attached read/write head. The rotatable frame is attached to a fixed post on the substrate by relatively stiff torsional springs. A piezoelectric driver having a fixed end attached to the substrate provides bidirectional linear displacement of its movable end. The microactuator has a displacement amplification mechanism that includes a connecting rod and a linkage that translates the linear displacement of the driver to amplified orthogonal linear displacement of the rod. The connecting rod is attached to the rotatable frame at a radial distance to cause rotary movement of the frame, and thereby cross-track displacement of the read/write head on the slider.

A rotatable frame that supports the slider is attached to a fixed post on the substrate by relatively stiff torsional springs. A piezoelectric driver having a fixed end attached to the substrate provides bidirectional linear displacement of its movable end. The microactuator includes a displacement amplification mechanism. In one embodiment an arm or connecting rod is located between the driver's movable end and the frame. A linkage between the movable end of the driver and a first end of the connecting rod translates the linear displacement of the driver to amplified orthogonal linear displacement of the rod. The second end of the rod is attached to the rotatable frame at a radial distance to cause rotary movement of the frame, and thereby cross-track displacement of the read/write head on the slider.

摘要： Embodiments of the present invention help to suppress reduction of the operation quantity of a microactuator. According to one embodiment, a microactuator comprises a silicon substrate and a piezoelectric element. The silicon substrate has some rigidity and provides elastic counter force to the piezoelectric element. In the piezoelectric element, a secondary piezoelectric layer is laminated on a primary piezoelectric layer opposite from the silicon substrate. The contraction force of the secondary piezoelectric layer acts on the primary piezoelectric layer so that it bends toward the secondary piezoelectric layer opposite from the silicon substrate. When the primary piezoelectric layer expands, the contraction force of the secondary piezoelectric layer acts on the primary piezoelectric layer so that it warps against the primary piezoelectric layer.

摘要： Embodiments of the present invention relate to approaches to effectively let noise on a head slider bonded to a silicon substrate of a microactuator, escape to the ground. A head gimbal assembly (HGA) according to an embodiment of the present invention comprises a microactuator bonded to a gimbal tongue. The microactuator comprises a piezoelectric element and a movable part for moving in response to expansion or contraction of the piezoelectric element. The motion of the movable part causes a head slider to slightly move. The microactuator further comprises a conductive path including an impurity-containing silicon layer formed on the silicon substrate. The conductive path transmits electric charge of the head slider to a suspension. The conductivity of the impurity-containing silicon layer is lower than the one of the silicon substrate so that the noise charge of the head slider may escape to the suspension.
