  • Patent number: 9086858
    Abstract: A disk drive can include an enclosure and a media disk rotatably mounted to the enclosure via a spindle. A fluid dynamic bearing (FDB) can be mounted between the enclosure and the spindle of the media disk. The FDB may include an integrally formed shaft and lower thrust bush formed together from a single material.
    Type: Grant
    Filed: November 26, 2013
    Date of Patent: July 21, 2015
    Assignee: HGST NETHERLANDS B.V.

  • Patent number: 7477489
    Abstract: An actuator assembly for use in a disk drive includes a first read head and a coarse actuator. The coarse actuator includes a coarse actuator body and a first actuator arm extending away from the coarse actuator body. The first actuator arm has a proximal end attached to the coarse actuator body and a distal end. The actuator assembly further includes a first microactuator attached to the distal end of the first actuator arm. The first microactuator supports the first read head. The actuator assembly further includes a first force-balancing microactuator attached to the distal end of the first actuator arm without any read head attached to the first force-balancing microactuator.

  • Patent number: 6967800
    Abstract: A disk drive suspension assembly. The suspension assembly includes a load beam and a base plate with a longitudinal axis. The base plate includes an actuator arm and an opposing actuator arm end. The head gimbal end is disposed in mechanical communication with the load beam for distally supporting the load beam. The head gimbal end defines opposing first and second distal corners. The base plate includes first and second mass reduction openings formed through the base plate symmetrically about the longitudinal axis at the head gimbal end for locally reducing mass to mitigate torsional vibration mode frequency about the longitudinal axis. The first mass reduction opening is disposed at the head gimbal end between the first distal corner and the longitudinal axis. The second mass reduction opening is disposed at the head gimbal end between the second distal corner and the longitudinal axis.
