  • Independently driven write coils
    Patent number: 8947807
    Abstract: A writer assembly having two separately driven write coils allows a combined write field generated by the writer assembly to be fine turned and optimized for a particular application. Two preamplifiers may be incorporated into a printed circuit board in order to separately drive the write coils. In other implementations, there may be more than two write coils and corresponding preamplifiers.

  • Data Writer with Yoke Shaped Write Pole
    Publication number: 20140300995
    Abstract: A magnetic element can be configured as a data writer with at least a write pole contacting a yoke and having an air bearing surface. The write pole may be shaped to match a paddle surface of the yoke that extends perpendicular to the air bearing surface and facing parallel to the air bearing surface.

  • Magnetic device containing a heater
    Patent number: 8760808
    Abstract: An apparatus that includes a writer that includes a write pole, at least one return pole, a writer coil and a write pole tip, wherein the write coil wraps around the write pole such that the flow of electrical current through the write coil generates a magnetic flux at the write pole tip, and wherein the write coil has a writer coil shape; and a heater that includes a resistive material, wherein the heater has a heater shape that substantially matches the writer coil shape.

  • Sensor stripe encapsulation layer in a read/write head
    Patent number: 6935923
    Abstract: A magnetoresistive read head has read head layers that are shaped to form an air bearing surface and a sensor stripe cavity with an open side at the air bearing surface. A sensor stripe is deposited in the sensor stripe cavity. The sensor stripe has a front surface that is set back from the air bearing surface to define an encapsulation cavity extending from the front surface to the air bearing surface. An encapsulation layer is deposited in the encapsulation cavity. The encapsulation layer encapsulates the front surface.
