  • Patent number: 7193819
    Abstract: A head stack assembly (HSA) is disclosed for use in a disk drive comprising a disk, wherein a merge tool is used to merge the HSA with the disk. The HSA comprises at least one actuator arm with a suspension connected to the distal end of the actuator arm. A multi-level shipping comb attached to the actuator arm comprises a finger having a first surface and a second, raised surface. During shipping of the HSA, the first surface of the finger contacts the suspension to protect against overstressing. During manufacture of the disk drive, the shipping comb is actuated so that the second surface contacts the suspension thereby bending the suspension in a vertical direction to facilitate the insertion of the merge tool.

  • Patent number: 6972924
    Abstract: A disk drive is disclosed employing a primary actuator for rotating an actuator arm about a pivot in coarse movements, and first and second secondary actuators coupled to the actuator arm for actuating first and second heads in fine movements. A servo control system generates a first control signal applied to the first secondary actuator to position the first head over the first disk surface in fine movements while accessing the first disk surface. The servo control system phase shifts the first control signal by a predetermined phase to generate a second control signal applied to the second secondary actuator to attenuate excitation of at least one arm vibration mode.

  • Patent number: 6938326
    Abstract: A suspension load beam for an actuator assembly of a disk drive includes a bend radius portion with a spring rate that is less than 18 Newtons per meter, a first bending mode that is greater than 3,500 Hertz, and a first torsion mode that is greater than 5,300 Hertz. The method of making this suspension load beam includes cutting a sheet of material to form a flat suspension load beam including a bend radius portion, removing material in the bend radius portion from full thickness, inspecting the bend radius portion to determine its thickness, and removing material from the bend radius portion and/or from the main body of the suspension load beam to compromise the performance difference due to thickness variation in bend radius portion.

  • Publication number: 20040204696
    Abstract: The present invention relates generally to an absorbent composite for an absorbent article, and more particularly to an absorbent composite comprising fibrous material and superabsorbent material having a Column Absorbency Under Load (CAUL) above 10 g/g. Such an absorbent composite provides a superabsorbent material having superior AUL and permeability, thereby providing improved absorption and rewetting properties. An absorbent article that contains such a composite provides improved ability to absorb and retain fluids, thus preventing excessive rewetting and leakage and making the article more comfortable to wear.

  • Patent number: 6445545
    Abstract: A slider support structure is disclosed for minimizing off-rack due to disk flutter. In one embodiment, the slider support structure includes a gimbal assembly (306). The assembly (306) includes an outer ring (500) and an inner ring (502). The outer ring (500) is connected to the inner ring (502) via narrow strips (504 and 506) adjacent to the front (508) and back (510) surfaces of the slider body (512). The inner ring (502) is attached to the left (514) and right (516) surfaces of the slider body (512) via narrow strips (518 and 520). The strips (504 and 506) interconnecting the inner ring (502) and outer ring (500) define a flexible hinge that allows the slider body (512) to pivot relative to the assembly (306) about an axis (522) which, in this case, is the roll axis. Similarly, the strips (518 and 520) define a flexible hinge which allows the slider to pivot relative to the assembly (306) about another axis (524) which, in this case, is the pitch axis.
