  • Patent number: 7876519
    Abstract: 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.

  • Patent number: 7239475
    Abstract: A disk drive including a disk drive base, a disk coupled to the disk drive base, and a head stack assembly coupled to the disk drive base. The disk drive further includes an airflow diverter filter component disposed upstream of the head stack assembly with respect to disk rotation induced airflow for modifying the disk rotation induced airflow adjacent the head stack assembly. The filter component includes a first filter element disposed adjacent the disk surface, a second filter element disposed between the first filter element and the head stack assembly, and a third filter element having a porosity finer than the first and second filter elements. The third filter element is generally radially further than the second filter element from the axis of rotation. The disk rotation induced airflow generally enters the filter component through the first filter element and exits through the second and third filter elements.

  • Patent number: 6362932
    Abstract: 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.

  • Patent number: 6313967
    Abstract: A disk drive spindle air bearing is disclosed having increased bearing stiffness, while being capable of manufacture using conventional tolerances. The invention therefore allows the construction of a disk drive spindle bearing without the need for oil or grease that may potentially contaminate the storage disks. The disclosed disk drive spindle air bearing also provides an air bearing having low acoustical noise and power consumption characteristics.

  • Patent number: 5768784
    Abstract: A coating system and method for facilitating the cleaning of hydrodynamic bearings and their associated structure is effectuated by applying a surface energy lowering coating to selected portions of the bearing other than the surface tension seal producing gaps thereof prior to a lubricant fluid fill. The coating system and method of the present invention may also advantageously be utilized to produce a secondary barrier seal extending a relatively short distance within and adjoining the opening of the surface tension seal producing gaps.

  • Patent number: 5558445
    Abstract: 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.

  • Patent number: 5407281
    Abstract: 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.
