  • 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.
    Type: Grant

  • Multilayer acoustic damper for a disc drive
    Patent number: 6536555
    Abstract: A disc drive top cover incorporates an acoustic damper having alternating constraining layer material and damping layer material. Each constraining material layer is a sheet material having a high mechanical stiffness. Each damping material layer is a visco-damping adhesive having a pre-selected maximum damping efficiency for a particular disc drive operating condition. The acoustic damper may also include a carrier layer between damping layers so that multiple layers of damping material can be incorporated between any two constraining layers.

  • Threadably mountable drive actuator bearing assembly
    Patent number: 6525910
    Abstract: An actuator assembly suitable for a disc drive with at least one rotating disc for storing information. The actuator assembly has an actuator body having a mounting opening with at least a portion of the mounting opening being threaded and a bearing cartridge having an outer surface with at least a portion of the outer surface being threaded. The bearing cartridge is threadably received within the mounting opening of the actuator body so that the actuator body is releasably secured to the bearing cartridge. A method for securing an actuator body to a bearing cartridge in an actuator assembly of a disc drive is also provided.
