摘要： A head slider apparatus, to be attached to a magnetic head in a magnetic disc drive, for preventing bimodal stiction by preventing tipping of the head slider on its rear edge by forcing tipping of the head slider towards one of the head slider's corners. Subsequently, the head slider also mitigates any resultant stiction related to the corner tipping of the head slider that may occur. The head slider apparatus has a diamond-shaped pattern of four pads. The diamond-shaped pattern of the pads directs tipping of the head slider towards its corners. The head slider also has pads positioned in each corner of the head slider to address any resultant stiction caused by the corner tipping.

摘要： Tapered elements fabricated from a substrate of a size many times that of a single element are disclosed. Such tapered elements may be used as piezoelectric microactuators such as in-plane piezoelectric bimorph microactuators. A unique method of fabricating such tapered elements is provided. According to the method, cutting directions are first defined, the substrate is then cut a plurality of times in each cutting direction with adjacent cuts in each cutting direction indexed by proper indexing distances which are determined based on the dimensions of the final tapered elements. In one embodiment of the method, a plurality of optically detectable marks are used to define the cutting directions and cutting means is accordingly optically aligned with the cutting directions.

摘要： A gimbal-level piezoelectric microactuator including monomorphs for the fine positioning of a head-arm assembly of a disk drive. The microactuator is manufactured from a generally flat metal sheet structure having a central beam and two tabs extending from opposite sides of the beam. At least one layer of piezoelectric material is bonded onto each of the two tabs. Each of the two tabs is bent, with the piezoelectric layers bonded thereto, to a position substantially normal to the central beam. The structure is then joined to the distal end of a suspension member of the head-arm assembly. A recording head is connected to the central beam of a gimbal or flexure element and the microactuator is also attached to the flexure element. When a voltage is applied to the piezoelectric materials, deflection of the microactuator occurs, thereby positioning the recording head.

摘要： A microactuator is disclosed for selectively altering a position of a transducing head carried by a slider in a disc drive system with respect to a track of a rotatable disc having a plurality of concentric tracks. The disc drive system includes a head mounting block for attachment to an actuator arm and a head suspension supporting the slider over the rotatable disc. The microactuator includes a piezoelectric element attached between the head mounting block and the head suspension and beams connecting the head mounting block and the head suspension. The piezoelectric element is deformable in response to a voltage applied thereto. The beams are flexible to permit movement of the head suspension with respect to the head mounting block upon deformation of the piezoelectric elements, and have heights extending out of the general plane of the head mounting block and the head suspension.

摘要： A suspension for connecting a slider to an actuator arm of a disc drive and for maintaining the slider substantially engaged with a disc surface positioned below the suspension incorporates a load beam defining a first bend region adjacent a proximal end of the load beam and a second bend region adjacent a distal end of the load beam. An overlapping member attached to a top surface of the load beam has a first segment fixed to the load beam on one side of the second bend region and a second segment that engages the load beam on the other side of the second bend region when the distal end of the load beam is placed under a load in the absence of a shock event. The second segment of the overlapping member disengages from the surface of the load beam during a shock event to allow the second bend region to help absorb the shock and maintain the slider engaged with the disc surface.

摘要： A disc drive suspension incorporates a loadbeam with a shorter bend section having higher torsional stiffness and higher-frequency resonance states than conventional suspension bend sections. The bend section is formed by etching a narrow groove in the loadbeam. The suspension may also include a separate bend section piece that bridges a gap between the loadbeam anchor sheet and the loadbeam. A method of performing a pre-load adjustment on a transducer suspension for use in a disc drive includes attaching a loadbeam anchor sheet of the suspension to an actuator arm of an E-block to form part of an actuator assembly, measuring a pre-load force on the suspension on the actuator arm, back-bending the suspension until the bend section yields and measuring the pre-load force on the suspension on the actuator arm.

摘要： An apparatus for minimizing corrosion product build-up within a disc drive incorporates a non-corrosive gas hermetically sealed within the disc drive and a diaphragm chamber that allows the constrained non-corrosive gas to respond to changes in pressure and temperature. The diaphragm chamber includes a diaphragm that partitions the diaphragm chamber into a top and bottom chambers. The top chamber has an aperture for communicating with the external environment and the bottom chamber has an aperture for communicating with the internally constrained non-corrosive gas. The diaphragm is non-permeable and made of an elastic material that responds to changes in air volume or mass on either side of the partition so that the pressure inside the hermetically sealed disc drive is constant throughout the life of the device. The diaphragm chamber can be located inside or outside the disc drive and can be integrally formed within the top cover of the disc drive.
