  • Disc drive pivot bearing assembly
    Publication number: 20040246627
    Abstract: An actuator assembly has a generally flat sheet metal body with upper and lower surfaces and an actuator bore passing therebetween. The actuator bore is sized to receive the bearing cartridge assembly therethrough. A plurality of tabs project inward from an interior surface of the actuator bore, wherein the tabs extend only partially along a depth of the actuator bore between the upper and lower surfaces. The tabs contact the bearing cartridge assembly and secure it within the actuator bore.

  • Damper for disc drive voice coil motor
    Patent number: 6608732
    Abstract: A disc drive device includes a base plate having an upper surface, a voice coil motor operably attached to the upper surface of the base plate, and a damper pad positioned on the upper surface of the base plate between the base plate and the voice coil motor such that vibrations occurring in the base plate and/or the voice coil motor are effectively damped. In this manner, vibrationally induced noise in a disc drive servo system and vibrationally induced acoustical emissions from the disc drive device are reduced.
