  • Patent number: 7624495
    Abstract: A lubricant is applied to swage contact surfaces in a disk drive of the type including a suspension arm connected to an actuator arm by a swaging process. A preferred thin film lubricant may be applied to the contact surfaces by immersion and draining, immersion and raising the part out of the solution, localized spraying, or various deposition processes. Application of the lubricant reduces chipping during de-swaging, particularly with nickel plated metal components. Application of the lubricant has also shown to improve gram load uniformity, reduce adverse distortion to the actuator assembly and reduces torque out retention values. Improved gram load uniformity enhances overall disk drive functioning, reduced distortion preserves intended attitude and flatness of the actions for assembly and reduced torque out retention values improves reworkability of the disk drive.

  • Patent number: 7024754
    Abstract: A method is provided for assembling an actuator assembly of a disk drive. The method includes providing an actuator arm, providing a suspension arm, fixing a swage plate to the suspension arm, the swage plate including a swage boss extending therefrom, depositing a film lubricant upon at least an outer surface of the swage boss, and attaching the suspension arm to the actuator arm by swaging. A method is also provided for reducing torque out retention values between the actuator arm and the suspension arm when the actuator arm and suspension arm must be separated in a subsequent de-swaging process. This method includes providing an outer surface of the swage boss, and applying a lubricant film coating to the outer surface of the swage boss. A preferred thin film lubricant may be applied by emersion and draining, localized spraying, or various deposition processes.

  • Patent number: 6954978
    Abstract: A method is provided for protecting a head element of a computer disk drive during rework operations by applying thioropolymeric protective coating or film to the head element after the disk drive has been opened. Application of the protective coating is preferably performed utilizing a solvent-mediated deposition process. Further aspects of the invention include the application of the protective coating to the head element prior to storage of the head element or prior to shipping the head element in order to facilitate rework of the head element or other components of the disassembled disk drive.

  • Patent number: 6214070
    Abstract: The filter assembly of the present invention provides protection to a data storage disk drive assembly from contaminants, including chemical gases and particles, that either enter or exit the disk drive assembly. Incoming gases and particles pass through a label, into a hard body filter, through a diffusion filter, contact the chemical adsorbent and pass into the drive interior through a particulate filter. Outgoing gases and particles go through the apparatus in reverse. The filter assembly may be installed from the outside of the disk drive assembly at a chosen location and at any point during or after manufacturing and testing. The filter assembly is held in place by lateral extensions and an adhesive label applied to the exterior mounting surface.
