    摘要： A device comprises a recordable disc, a substrate adjacent to the recordable disc, and an actuation mechanism fixed to the substrate. The recordable disc includes a base layer and a recordable layer on the base layer. Additional electrodes or magnetic components may be placed on the base layer to provide electromagnetic or electrostatic forces to rotate the recordable disc when acted on by the actuation mechanism. As an example, the invention may utilize MEMS techniques in order to integrate a disc and motor of a disc drive as a common component.

    摘要： A method and system for positionally displacing a transducer, or multiple transducers, over a location on a data storage medium is disclosed. An actuator assembly containing at least one actuator arm supporting at least one transducer is used to access a desired location on the data storage medium. The actuator arm contains an intrinsically excitable element, such as piezoelectric material, responsive to a control signal to produce an excitement. The excitement in the element generates a movement of the element that is magnified by a flexure to positionally displace the transducer, which is attached to the flexure. The transducer is displaced from a current, or origination, location to the desired location.

    摘要： A device comprises a fluid bearing including a textured fluid bearing surface and a second surface and a recordable disc. The recordable disc includes a substrate, a recordable media layer on the substrate, and at least one of the textured fluid bearing surface and the second surface. The device may be manufactured using MEMS techniques. MEMS techniques provide the high precision necessary to create the textured fluid bearing surface. MEMS techniques also allow the recordable disc to be batch-fabricated with one or more additional recordable discs.

    摘要： A disc drive device includes a base plate, a voice coil motor operably attached to the base plate, a top cover attached to the base plate with at least two perimeter fasteners and at least one interior fastener, wherein the two perimeter fasteners and the interior fastener form a triangular portion of the top cover therebetween, a pressure seal sealing the top cover and the base plate, and an acoustic damper contacting the voice coil motor and the triangular portion of the top cover for damping vibrations occurring in the voice coil motor and the top cover. The acoustic damper is made of the same material as the pressure seal. In this manner, vibrationally induced acoustical emissions from the disc drive device are reduced.

    摘要： A top cover formed from a metal matrix composite material for use on a data storage device is disclosed. The metal matrix composite material includes a porous matrix material combined with an inclusion material constrained within the pores of the porous matrix material. The porous matrix material is substantially aluminum while the inclusion material is a ceramic such as silicon hexaboride or aluminum boron carbide capable of wetting molten aluminum. The ceramic inclusion material is selected to have a specific modulus greater than the specific modulus of the porous metal matrix such that the entire volume of porous matrix material provides acoustical dampening during operation of the data storage device.
