  • Patent number: 8840730
    Abstract: A machine for cleaning a head-disk assembly (HDA) of a hard disk drive (HDD) includes a nest that seals the HDA between an upper and lower portion during cleaning. An inlet port receives a gas and an exhaust port exhausts the gas and entrained particles. A shock drive delivers mechanical shocks to the nest and the HDA while the gas is flowing through the HDA. A blower may circulate the gas from the exhaust port to the inlet port. A filter may be coupled to the inlet port. The HDA nest may be movable along an axis of the mechanical shocks delivered by the shock drive. A blow tube may deliver gas to a screw hole and a coaxial vacuum tube may rest against a surface around the screw hole to encapsulate the blow tube during cleaning and remove the gas and particles from the screw hole.

  • Patent number: 7921543
    Abstract: A method of manufacturing a disk drive is disclosed. After installing at least one disk into a base, a media cover is coupled to the base, wherein the media cover covers at least a portion of the disk. After coupling the media cover to the base, a head coupled to an actuator arm and a voice coil motor for rotating the actuator arm about a pivot is installed into the base. After installing into the base the head coupled to the actuator arm and the voice coil motor, the media cover is removed from the base. After removing the media cover from the base, a HDA cover is coupled to the base to form a head disk assembly (HDA).

    Abstract: A method is disclosed for manufacturing a disk drive. At least one disk is installed into a base, and a media cover is coupled to the base, wherein the media cover covers at least a portion of the disk. After installing the media cover, a head coupled to an actuator arm and a voice coil motor for rotating the actuator arm about a pivot are installed into the base. The media cover is then removed and an HDA cover is coupled to the base to form a head disk assembly (HDA). In one embodiment, the base comprises an aperture, and coupling the media cover to the base comprises inserting a pin into the aperture. In one embodiment, the aperture is also for coupling a printed circuit board to the base after removing the media cover.
