  • MEMS disc drive
    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.

  • Interconnect architecture for disc drive array
    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.

  • Recording head for reducing side track erasure
    Publication number: 20090251827
    Abstract: The present invention relates to a head having an air bearing surface for confronting the surface of a storage medium. The head includes a first pole that is spaced apart from a second pole. At least one non-magnetic spacer is positioned between the first pole and the second pole such that the first pole is magnetically decoupled from the second pole. In a further aspect, one or both of the first pole and the second pole can be elliptical in shape.

  • Transducing head including a magnetic element exhibiting varying permeability
    Patent number: 7561380
    Abstract: A transducing head has a main pole and at least one magnetic element (such as a return pole or a shield) which provides a potential return path for a magnetic field produced by the main pole. The magnetic element is spaced from the main pole. The magnetic element has a first edge closest to the main pole and a second edge furthest from the main pole. Permeability of the magnetic element increases from the first edge to the second edge.
