摘要： A lubricant reservoir for a vapor transport type rigid magnetic disk drive lubricant system includes a metal heat sink that presents a finned surface at the side exposed to the outside environment. A second surface within the sealed head-disk enclosure cooperates with a thermal heat transfer resisting wall portion to form a duct. A lubricant reservoir is retained against the heat sink surface within the duct. The reservoir assembly is secured to the head-disk enclosure wall by mounting tape that not only seals the enclosure, but thermally isolates the reservoir assembly from the enclosure wall. The reservoir assembly is further positioned adjacent the disk assembly of the drive such that disk rotation induces an air flow through the reservoir duct and in contact with the lubricant reservoir to effect vapor transport between said reservoir and disks to maintain a proper molecular layer of lubricant on the disk surfaces which are always maintained at a temperature greater than the reservoir during disk drive operation.

摘要： A disk drive or direct access storage device (DASD) of the type having multiple disks and multiple actuator arms, both the disks and the actuator arms assembled in a stacked manner, advantageously assembled with the locating surface or flange of the actuator disposed on the opposite side of the stacked actuator arms from the side of the disk stack having the locating surface or flange for the disk hub. This opposite flange design results in a substantial reduction in the effects of tolerance buildup and therefore permits the design of the disk drive equal in all other respects to a conventional same side flange arrangement, but permitting additional disks, lower height, less tightly defined tolerances on components or the use of cheaper manufacturing techniques and technologies for recording data.

摘要： The magnetic disk drive chemical breather filter of the present invention affords protection with respect to chemical vapors and gases in addition to trapping particulate pollutants. The chemical filter as described, protects against both organic vapors and inorganic gases. In addition particulate filters are interposed between the chemical filters and both the exterior atmosphere and internal atmosphere. The combined filter is isolated from both external and internal atmosphere by extended length diffusion passages. Both difffusion passages are composed of multiple parallel paths to prevent the blockage of any single path from impairing the functioning of the filter. Chambers formed at each side of the combined filter medium and access thereto by the diffusion passages at the center of one chamber and the periphery of the other enables the length of the air passage through the filter medium to be equal irrespective of the portion of the filter through which the air flow passes. Using an activated carbon fabric chemical filter and coplanar multiple diffusion paths, a low profile, low cost filter assembly is achieved. The use of ultrasonic welding of the parts eliminates connector devices and adhesives as sources of contamination.

摘要： A magnetic disc storage system includes a magnetic storage disc and a transducing head. During periods of inactivity the transducing head is dithered whereby the head is moved to tracks on the disc according to a number of criteria. The criteria includes wear reduction, power reduction, avoidance of textured zones, head cycling, increased fly height and clearing of debris carried on the head.

摘要： A resilient and compliant shock rail is provided on the sides of the bottom cover for a PCMCIA standard Direct Access Storage Device. The shock rails, being of a resilient and easily deformable material, lengthen the impact time and attenuates the shock forces exerted on the DASD, thereby bringing the deceleration forces to acceptable levels. The shock rail may be further provided with low friction surfaces by bonding thin metal plates to the top and bottom surfaces of the shock rails to ease insertion and withdrawal of the PCMCIA DASD. The shock rail is provided with reinforcing members to insure that the keying scheme required for proper insertion is effective.
