    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.

    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.

    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. Other thermodynamic apparatus including stand alone compressors and heat pumps are described.

    Abstract translation: 压缩机和热泵组合具有活动室和被动室，每个室具有自己的热板和冷板。 两个腔室沿着边缘连接，其膜大大地传递压力，绝大部分绝热而不能传递温度，并且防止气体从一个腔室通到另一个腔室。 主动室中的气体交替地被冷却并通过暴露于活性冷和活性热板进行加热，从而导致活性室中的压力变化，其通过膜传递至被动室。 压力变化交替地将被动室中的气体冷却到被动冷板的温度以下，并将被动室中的气体加热到被动热板的温度以上。 在将被动室中的冷却气体交替地暴露于被动冷板，将被动室中的被加热气体暴露于被动热板时，迫使热量从被动冷板流向被动热板。 描述了包括独立压缩机和热泵的其它热力学设备。

    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.

    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.
