Us Patents

  • Disk Drive Having A Disk Limiter That Is Disposed Within An Angular Range Relative To A Base Depression Brim

    view source
  • US Patent:
    8289646, Oct 16, 2012
  • Filed:
    Jun 24, 2010
  • Appl. No.:
    12/822452

  • Assignee:
    Western Digital Technologies, Inc. - Irvine CA
  • International Classification:
    G11B 33/14
  • US Classification:
    360 9715
  • Abstract:
    A disk drive includes a spindle that defines a spindle rotation axis, and a disk drive base that has a base depression bounded by a first base depression brim. A disk is attached to the spindle, and the disk includes a disk outer peripheral extent. The disk drive includes a disk limiter protrusion extending over an arc of the disk outer peripheral extent that spans no more than 20 about the spindle rotation axis. According to one aspect of the invention, a first radius that extends from the spindle rotation axis over the first base depression brim is angularly disposed no more than 25 from any second radius that extends from the spindle rotation axis to the disk limiter protrusion. According to another aspect of the invention, the disk limiter protrusion may protrude from an edge of a VCM yoke top plate towards the spindle rotation axis.

  • US Patent:
    8416534, Apr 9, 2013
  • Filed:
    Jun 30, 2010
  • Appl. No.:
    12/828103
  • Inventors:
    Baekho Heo - San Jose CA, US

  • International Classification:
    G11B 5/55
  • US Classification:
    3602656
  • Abstract:
    Described herein is a tolerance ring for a disk drive that includes a substantially cylindrical body having outer surface. The tolerance ring can be positioned between a rotational bearing and an actuator for providing rotational movement of the actuator. The tolerance ring can also include a contact member, positioned along the outer surface, that protrudes outward from the outer surface. The contact member can be connected to the outer surface by first and second angulated arms that extend from the outer surface to the contact member at different angles relative to the outer surface.

  • International Classification:
    G11B 33/14
  • US Classification:
    360 9714
  • Abstract:
    Described herein is a disk drive having a disk receiving surface with an outer diameter. The drive can include a peripheral edge that extends transverse to the disk receiving surface and circumferentially about at least a portion of the outer diameter of the disk receiving surface. The drive can also include a disk limiter that extends between and transverse to the disk receiving surface and the peripheral edge to provide a transition between the disk receiving surface and a surface of the peripheral edge.

  • US Classification:
    360 9918, 360 9712, 360 9719, 360 972, 360 9915
  • Abstract:
    A disk drive including a disk having a top surface, a cover positioned over the disk, and a disk limiter protruding from the cover toward the disk. The disk limiter is configured to contact a portion of the top surface of the disk when the disk is deflected toward the cover, and has a middle portion between two end portions. At least one portion of the disk limiter curves or slopes in a direction away from the disk.

    G11B 33/08
  • US Classification:
    360 9719, G9B 33024
  • Abstract:
    A disk drive including a disk having a bottom surface and a base having a first surface lying along a first plane and a second surface lying along a second plane positioned substantially parallel to the first plane. The second surface is spaced apart from the first surface and is beneath at least a portion of the bottom surface of the disk. A damper of the disk drive is located on the second surface adjacent the first surface and is configured to contact a portion of the bottom surface of the disk when the disk is deflected toward the first surface.
