摘要： A method for erasing a disk of a hard disk drive. The method includes moving the hard disk drive adjacent to an erasure head that emanates a magnetic field. The magnetic field and moving hard disk drive cause a disk of the hard disk drive to spin under a Lorentz force created by the magnetic field and moving disk. The magnetic field is applied by the erasure head for a duration that causes erasure of the entire disk. The spindle motor is not activated during the entire process. Not activating the spindle motor eliminates any Faraday coupling from the erasure head into the motor.

摘要： A disk drive spindle air bearing includes an air bearing gap between a pair of air bearing surfaces that varies as a function of radial distance from an axis of rotation. This non-uniform air bearing gap effectively minimizes contact between the air bearing surfaces of the bearing when the disk drive hub is at rest or spinning below a threshold speed. This reduced contact significantly reduces the stiction forces that must be overcome during disk drive spin up operations and also reduces the generation of wear particles within the bearing. Air bearing surface shaping techniques are provided for achieving the non-uniform gap dimension, including techniques involving crowned, stepped, and sloped surfaces. In an alternative approach, sacrificial plating is employed to achieve a non-uniform gap dimension within the air bearing.

摘要： A self-contained hydrodynamic bearing unit includes a shaft and a shaft housing defining an opening for receiving the shaft for relative rotation. The shaft and bearing define at least one radial hydrodynamic bearing and an annular thrust bearing, formed as a disk portion extending radially outward of a main cylindrical surface of the shaft which cooperates with an adjacent annular face of the shaft housing. A gap between an outer cylindrical wall of the thrust bearing disk portion and an adjacently facing cylindrical surface of the shaft housing provides a primary annular capillary seal segment. An annular bushing ring extends from the housing radially inwardly to enclose the thrust bearing disk, and cooperates with an adjacent outer face of the thrust bearing disk to provide a secondary containment capillary seal segment. Normally, lubricating liquid is in the bearing unit at the radial hydrodynamic bearing, at the hydrodynamic thrust bearing and in the primary annular capillary seal segment. However, if liquid overflows from, or extends beyond the primary seal segment as by thermal expansion, it is contained in the secondary seal segment and urged to return by centrifugal force to the primary seal segment. A tertiary containment seal may also be provided to prevent escape of liquid to the external ambient.

摘要： A self-replenishing hydrodynamic bearing unit comprises a shaft and housing defining an opening for receiving the shaft for relative unidirectional rotation. A plurality of reservoirs contain a lubricating fluid. A hydrodynamic bearing region lies between the plurality of reservoirs for providing a rotational journal for relative rotation between the shaft and the housing. At least one of the shaft and the housing defines a continuous pattern of herringbone or Vee-shaped pumping grooves or passages which communicate between the plurality of reservoirs for pumping the lubricating fluid during relative rotation. The groove pumping creates a pressurized hydrodynamic bearing lubricant film at the bearing region with each groove generating localized unidirectional directional flow of lubricating liquid between the reservoirs along a predetermined axial direction of rotation, wherein some passages create axial flow in a forward direction and the others create axial flow in a reverse direction. The passages are arranged so that a total of the axial flows from all of the pumping passages is essentially zero.
