    Abstract: A data transducer is used for writing data to a disc and has an air bearing surface. The data transducer also includes a bottom pole and a top pole separated from the bottom pole at the air bearing surface by a write gap. A core is formed between the bottom pole and the top pole and a conductive coil is positioned within the core. The data transducer further includes an insulator conformed to turns of the conductive coil and a core fill deposited within the entire core wherein the core fill is a high-thermal conductivity material. The insulator and core fill dissipate thermal energy away from the conductive coil.

    Abstract: A transducing head according to the present invention includes a pair of electrodes, a pair of biasing elements and a magnetoresistive sensor. The magnetoresistive sensor is positioned between the pair of electrodes. The magnetoresistive sensor includes a pair of flux guides and a free layer positioned substantially co-planar with and between the pair of flux guides. The pair of electrodes are for providing a sense current to the free layer in a direction substantially perpendicular to a plane of the free layer. The pair of biasing elements are positioned on opposing sides of the magnetoresistive sensor for providing longitudinal bias to the free layer.

    Abstract: The disclosure relates to micro-electromechanical systems (MEMS) and magnetic MEMS sensors. The sensors include a substrate having a surface, a first magnetic field detector positioned on the surface, a second magnetic field detector positioned on the surface proximate to the first magnetic field detector, and a third magnetic field detector positioned on the surface proximate to the first and second magnetic field detectors. Each of the first, second and third magnetic field detector is capable of detecting external magnetic fields that are mutually orthogonal along three directions. In certain embodiments, the magnetic MEMS sensors may be useful as electronic compasses. The disclosure also relates to fabricating a magnetic MEMS device, such as an electronic compass, from or on a single wafer, which includes multiple MEMS sensors.

    Abstract: A magneto-resistive sensor has a magneto-resistive element with an active area with an electrical resistance sensitive to changes in magnetic flux. Two hard magnets on opposing sides of the magneto-resistive element magnetically bias the magneto-resistive element. Each hard magnet includes a seed layer of a soft magnetic, electrically conductive material between two magnet layers of a hard magnetic, electrically conductive material laminated longitudinally together such that the seed layer and the magnet layers exhibit unified magnetic properties. The seed layer is preferably an amorphous material such as nitrided sendust. The laminated structure allows for a thicker magnet structure with low electrical resistance but without degradation of magnetic properties due to the increased thickness.
