摘要： A novel actuator latch includes a catch portion interfering with actuator rotation with the latch in a closed position. The latch includes a first stop portion that is in contact with a fixed member with the latch in the closed position. The latch includes a pusher portion that is in contact with the actuator with the latch in the closed position and with the actuator in an extreme rotational position. The pusher portion has a torsional stiffness about the latch pivot location in the range 5 JA/rad·sec2 to 30 JA/rad·sec2, where JA is the rotational inertia of the actuator about the actuator pivot location expressed in units of kg·m2. The first stop portion has a torsional stiffness about the latch pivot location that is at least 5 times that of the pusher portion.

摘要： The disk includes a disk recording surface, and the ramp includes a ramp. A head stack assembly of a hard disk drive includes an actuator arm and a suspension assembly attached to the actuator arm. The suspension assembly includes a first elongated region having a distal region and a planar surface for facing toward the disk recording surface; the first elongated region defines a longitudinal axis. The suspension assembly includes a second elongated region positioned adjacent to the distal region. The second elongated region includes a lift tab for engaging the ramp surface and is vertically offset from the planar surface such that the lift tab is vertically displaced further from the disk recording surface than the planar surface. The second elongated region further includes a curved lift tab supporting member for supporting the lift tab and positioned between the distal region and the lift tab. The lift tab supporting member includes a first region integrally formed with the distal region, a second region integrally formed with the lift tab, and a third region positioned between the first and second regions such that the second region is vertically offset from the first region. The third region defines a first trough for stiffening the supporting member. The distal region and the first region define a second trough for stiffening the distal and first regions. The second trough extends along the direction of the longitudinal axis and has an outer surface for facing toward the disk recording surface, the outer surface being vertically displaced closer toward the disk recording surface than the planar surface.

摘要： Disclosed herein are disk drive spindle motors and disk drives using same that include one of more structures that function as travel limit stops that are designed to transfer the load created by a shock impulse to non-essential mechanical features and bypass the bearing structures, thereby keeping the load imposed thereon by the shock impulse below damaging levels. The spindle motor may also include one or more compliant members between the bearing structures and facing surfaces. Such compliant members may be combined with pre-load keepers that preload the bearings by axially compressing the compliant members.

摘要： A disk drive includes a ramp having a fixed portion that is fixed to the disk drive base, and a guide portion that is not. The guide portion includes a guide surface having a parking region that is in contact with an HGA lift-tab with the disk drive in a non-operational state. The guide surface also has a load/unload region that extends over a disk outer periphery. The guide surface defines a guide surface length that is measured from the parking region to the load/unload region. The ramp also includes a torsionally-compliant member connecting the fixed portion to the guide portion. A distance between the torsionally-compliant member and the parking region, measured approximately parallel to the guide surface length, is less than half the guide surface length. The guide portion is not connected to the fixed portion over at least two-thirds of the guide surface length.

摘要： A head disk assembly for a hard disk drive employs a rotary actuator apparatus including a pivot shaft that defines an actuator axis of rotation. A pivot bearing assembly including a pivot bushing having a plurality of fingers supports rotation of the actuator about the pivot shaft. Each of a plurality of fingers has a bearing end that is in sliding contact with the pivot shaft. The fingers are formed from a material in a shape that provides the stiffness and low coefficient of friction necessary for the desired pivot bearing performance.

摘要： A fastener comprises a shaft extending along a longitudinal axis, and a sleeve wrapped partially around the shaft. The sleeve comprises an inner surface adjacent the shaft, an outer surface, an upper extent, a lower extent, a first circumferential extent, a second circumferential extent, and a gap extending longitudinally from the upper extent to the lower extent and separating the first circumferential extent from the second circumferential extent. The sleeve has a first thickness adjacent the first circumferential extent that is less than a second thickness between the second circumferential extent and the first circumferential extent. A cross-sectional centroid of the shaft between the upper extent and the lower extent is in substantially the same location, with the sleeve in different first and second rotational positions.
