摘要:
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.

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.

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.

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.

A method is used for fabricating sliders for use in a disc drive actuation system, the sliders having bonds pads formed on either a top surface or side faces of the slider. The method comprises providing a substrate having a top surface. Trenches are formed in the substrate and filled with a bond pad material to form slider bond pads. Excess bond pad material is removed from the trenches such that the slider bond pads are flush with the top surface of the substrate. A transducer is fabricated on the top surface of the substrate. Finally, the slider bond pads are exposed.

A device for accessing data stored on a medium includes a substrate that has a transducer on a back side, a bottom side facing the disc, and a surface that protrudes from the bottom side. An insulation layer is placed on top of the surface. An electrostatic actuator electrode is placed on top of the insulation layer. The electrostatic actuator electrode faces the medium across an electrostatically charged portion of an air layer. The electrostatic actuator electrode protrudes above the surface into the electrostatically charged portion of the air layer.
摘要:
One embodiment of the present invention pertains to a slider that includes an aerodynamic surface which includes a first bearing surface, a cavity floor, and a first recessed pressurization surface. The first bearing surface is disposed on the aerodynamic surface, defining a bearing height. The cavity floor is disposed on the aerodynamic surface at a cavity depth below the bearing height. The first recessed pressurization surface is adapted to provide above-ambient fluid pressure when the slider is in nominal flight, which is greater than fluid pressure provided elsewhere on a trailing half of the aerodynamic surface at a substantial displacement from a longitudinal centerline of the aerodynamic surface. The first recessed pressurization surface is disposed on the aerodynamic surface at a recessed depth which is between the bearing height and the cavity depth.
