  • Patent number: 7965589
    Abstract: 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.

  • Patent number: 7957091
    Abstract: 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.

  • Patent number: 7835110
    Abstract: A micro-electromechanical systems (MEMS) disc drive includes high-precision and integrated components to allow for increased functionality, robustness and reduced size as compared to currently produced disc drives. Integrating multiple subcomponents of the disc drive using batch processing provides low manufacturing costs. Furthermore, using MEMS techniques, new features can be added to disc drives. For example, an environmental control component, an accelerometer and/or a thermometer may be integrated into the housing of the disc drive.

  • Patent number: 7826171
    Abstract: In general, the invention is directed to techniques for integrated interconnects with a set of disc drives. The interconnects allow for a set of disc drives to be positioned in an array; for example, as set of disc drives may be stacked to communicate with a device through a single interface of the device. The interconnects may be formed as vias within the housing of the disc drives. Vias may produced using MEMS techniques, e.g., electroplating, as part of the manufacturing processes of the disc drive itself.

  • Publication number: 20080062568
    Abstract: The application discloses processes for fabricating a slider or head for a data storage device. The processes disclosed provide a transducer portion that is separated from a slider body by a gap. In an illustrated embodiment, actuator elements are fabricated in the gap to adjust a position of the transducer portion relative to the slider body.

  • Publication number: 20070017247
    Abstract: A compressor and heat pump combination has an active chamber and a passive chamber, each with its own hot plate and cold plate. The two chambers are joined along an edge by a membrane that largely transmits pressure, largely insulates against temperature transfer, and prevents passage of gases from one chamber to the other. The gas in the active chamber is alternately cooled and heated by exposure to the active cold and active hot plates, causing pressure changes in the active chamber that are transmitted to the passive chamber by the membrane. The pressure changes alternately cool the gas in the passive chamber below the temperature of the passive cold plate, and heat the gas in the passive chamber above the temperature of the passive hot plate. In alternately exposing the cooled gas in the passive chamber to the passive cold plate, and the heated gas in the passive chamber to the passive hot plate, heat is forced to flow from the passive cold plate to the passive hot plate.

  • Publication number: 20060203387
    Abstract: A composite head-electrical conditioner assembly that includes a slider with a transducer head and transducer bond pads. The transducer bond pads communicate a transducer level electrical signal with the transducer head. An integrated circuit substrate has a conditioning circuit and first substrate bond pads electrically connected to the transducer bond pads. The integrated circuit substrate has second substrate bond pads with a conditioned electrical signal that is transmittable over a circuit. The slider is rigidly mounted to the integrated circuit substrate to form an assembly that is flexibly mountable. A thermal isolation space is provided between the transducer and the conditioning circuit. The integrated circuit can be in the form of a cap that provides windage reduction.

  • Publication number: 20050088784
    Abstract: A slider includes a slider body having a trailing edge and a leading edge. The slider also includes a thin film structure deposited in layers on the trailing edge. The thin film structure includes a write transducer configured to read and write to a storage medium. The thin film structure also includes a non-thermally activated actuator at least partially formed with the write transducer and configured to move the write transducer relative to the trailing edge.

  • Publication number: 20050083609
    Abstract: A slider for a data storage device is disclosed. The slider includes a bearing pad or surface having a raised bearing surface, a stepped bearing surface and a recessed pressure cavity or cavities. The recessed pressure cavity or cavities provides a reduced raised bearing surface area to reduce stiction and shape sensitivity. The recessed pressure cavity or cavities include a recessed cavity surface which is recessed from the raised bearing surface of the bearing surface or pad and a cavity step to the raised bearing surface.
