09/763688

Assignee:

Lanxide Technology Company, LP - Newark DE

International Classification:

B32B 1500

US Classification:

428614, 164 661, 164 681, 164 691, 164 91, 164 94, 164 97, 164101, 428621, 428627, 428926

Abstract:

Often, metal matrix composites (MMCs) lack adequate machinability and possess excessive abrasiveness because hard ceramic materials, such as silicon carbide, are used as the reinforcement phase. To make a metal matrix composite body having a more machinable and less abrasive surface, an MMC comprising an aluminum nitride reinforcement is formed on the surface of the body. In one embodiment, a layer is provided to a permeable mass or preform at the surface at issue, the layer featuring at least a reduced loading of ceramic filler material, and sometimes no ceramic material at all. The reduced loading is achieved by incorporating a fugitive material into the coating layer. Molten matrix metal is caused to infiltrate the permeable mass or preform and the coating layer to produce a macrocomposite body comprising a metal matrix composite coating and substrate. The metal matrix composite coating layer is distinguishable from the metal matrix composite substrate material, both compositionally and in terms of resulting properties. Under spontaneous infiltration conditions, as defined herein, aluminum nitride forms in-situ in the infiltrated body, including the surface layer.

International Classification:

US Classification:

360106

Abstract:

A shock-resistant actuator assembly for use in a data storage system is disclosed. The actuator assembly includes an actuator body, fabricated from a first type of metal, having a central aperture for pivoting on an actuator shaft. The actuator body includes at least one composite actuator arm extending outwardly from the actuator body. The composite actuator arm includes a primary arm member, also fabricated from the first type of metal, and a plating of a second type of metal having a thickness of at least 20 microns disposed on an upper and lower surface of the primary arm member. In one embodiment, the primary arm member is fabricated from aluminum and subjected to an electroless nickel plating process to deposit a sufficient thickness of nickel thereon to appreciably increase the stiffness of the primary arm member. In another embodiment, an actuator comb assembly includes a plurality of integral composite actuator arms for supporting a plurality of head suspension assemblies. The relatively thick plating of metal deposited on the primary arm member substantially enhances the stiffness and shock resistance of the composite actuator arm.

US Classification:

360105

Abstract:

A magnetic bistable latch mechanism for latching the actuator of a disk drive in a parked position is described. The latch comprises a magnetically detented latch lever which engages and latches a latch arm in a parked position. The latch arm is part of actuator motor structure and accordingly latches the actuator motor. The latch lever is held in either the latched or unlatched position by magnetic attraction and resists shocks and impacts that otherwise would move the actuator. The latch lever is shifted from one position t the other by the actuator motor eliminating the need for additional circuitry or mechanisms to control the latch. Additionally, the latch does not consume any electrical power in either the latched or unlatched condition.

US Classification:

360 9702

Abstract:

Disclosed is a disk drive having an enclosure for housing one or more disks, an actuator arm and sliders attached to the actuator arm. The sliders include magnetic transducers for reading information related to data off the disk and for writing representations of data to the disk. In a disk drive with an in-hub, fixed spindle shaft motor, the disk or disks are attached to the hub which is rotatably mounted to the spindle shaft. The hub includes one or more fingers attached to the hub which touch the spindle shaft when the hub is stationary and when the hub is rotating. The spindle shaft may also be provided with a wear resistant layer and/or ring of conductive material to enhance the electrical pathway between the hub and the spindle shaft and provide for lower wear and a longer life.
