摘要： A data storage device includes a memory storage disc, a spindle motor, a read head for sensing data stored on the disc, an actuator for supporting the read head with respect to the disc, and an air baffle between the actuator and the disc. The spindle motor rotates the memory storage disc causing air flow adjacent a surface of the disc. The air baffle is positioned between the disc and the actuator to isolate the actuator from the air flow adjacent the surface of the disc.

摘要： An actuator assembly for a computer disk drive includes a pivot shaft which defines a pivot axis for the actuator assembly, a pivotable actuator which encircles the pivot shaft, a bearing assembly disposed between the pivot shaft and the actuator, and a labyrinth seal adjacent to a lower edge of the bearing assembly. The labyrinth seal is incorporated into the pivot shaft and includes an axially extending ridge which is disposed in facing relation to a lower edge of the bearing assembly. The labyrinth seal also includes a reservoir disposed radially inwardly of the axially extending ridge, and a flange which extends radially outwardly of the axially extending ridge. The flange includes both axially and radially-facing surfaces which are disposed in facing relation to oppositely facing surfaces of the actuator. Very small air gaps are maintained between the labyrinth seal and the actuator assembly, on the order of 0.003 to 0.005 inch, in order to eliminate or minimize any actuator bearing lubricant migration or out-gassing into the disk drive assembly. An actuator shaft washer seal is provided adjacent to the upper edge of the bearing assembly. The actuator shaft washer seal is fixed to the actuator and extends radially inwardly toward the pivot shaft.

摘要： An apparatus and method for reducing the effects of disc flutter or noise in a disc drive incorporates damping material or rings that are clamped or sandwiched against mounted information storage disc at a distance from a hub portion of a spindle assembly. The damping rings are positioned between a disc clamp and a bottom annular flange of the hub portion so as to engage and reduce vibrations in the mounted information storage disc or discs. The damping rings can be retained in grooves defined in the disc clamp, bottom annular flange and top and bottom surfaces of an annular disc spacer. Alternatively, the damping rings can be reatined on tubular sidewalls defined on the disc clamp, bottom annular flange of the hub portion and annular disc spacer. The arrangement of damping rings absorbs energy transmitted by vibrations in information storage disc and thus minimizes the effects of disc flutter in a disc drive.

摘要： A clamp ring for a disk stack assembly of a computer disk drive unit includes a lower surface which includes an arcuate rolling contact surface that uniformly distributes a load applied to the clamp ring to components of the disk stack assembly underlying the clamp ring without damaging such disk stack components on load-induced flexion of the clamp ring. A cantilevered section of the clamp ring is disposed radially inwardly of the arcuate rolling contact surface, and is defined by a portion of the lower surface which is raised relative to an adjacent portion of the arcuate rolling contact surface so as to not contact the underlying disk stack components on load-induced flexion of the clamp ring. In use, the clamp ring is heated and then placed over the disk stack components to be clamped together. An axial load is applied to the clamp ring which causes it to flex and thus move contact between the lower surface of the clamp ring and the underlying disk stack components radially along the arcuate rolling contact surface. The axial force is maintained until the clamp ring cools sufficiently to hold the clamp ring in place, and then the axial load is removed.

摘要： An apparatus and method for minimizing the risk of damage to a disc surface caused by contact between a disc and a slider in a head disc assembly of a disc drive. The apparatus includes a flexure and slider which are biased away from the disc when the disc is stationary and one or more aerodynamic airfoils attached to the flexure. The airfoils are attached to the flexure and extend from the flexure at an angle relative to the disc so as to interact with an air flow caused when the disc spins to force the flexure and the attached slider to move toward the disc during operation of the disc drive.

摘要： A disc drive has rotatable recording disc and a transducing head on a slider arranged to fly over a surface of the disc when the disc is rotated. The slider is supported by an actuator arm operatively coupled to an actuator motor to position the transducing head over a selected track of the disc. The slider is arranged to land on the disc surface when the disc is not rotated. Dithering means vibrates the slider when the slider is on the disc surface to reduce stiction between the slider and the disc surface thereby reducing the torque required to commence flying of the slider.
