  • Magnetoresistive read sensor with short permanent magnets
    Patent number: 6930865
    Abstract: A transducing head has a magnetoresistive sensor, a first bias element, and a second bias element. The magnetoresistive sensor is positioned between the first and second bias elements, and has a sensor width. The first bias element has a first length and the second bias element has a second length. The direction of the first and second lengths are substantially similar to the direction of the sensor width. The first and second lengths in the range of about one-tenth to about twenty times the sensor width.
    Type: Grant

  • Differential VGMR sensor
    Patent number: 6556388
    Abstract: A Vertical Giant Magnetoresistive Sensor (VGMR) with two VGMR structures (61 A, 61 B), each responding differently to an external magnetic field, producing a differential signal proportional to the field. The magnetizations (M1, M1′, M2, M2′) in each of the sensors are oriented antiparallel. The antiparallel magnetization is attained by altering the magnetic compositions of the two structures, or adding an additional structure such as a permanent magnet or current strip (11) between the VGMR structures.

  • Composite lapping monitor resistor
    Patent number: 6364743
    Abstract: A lapping monitor resistor for thin film transducers that rely upon an insulation layer to define a critical dimension includes a first conductive layer having a plurality of conductive blocks, an insulating layer formed over at least a portion of the first conductive layer, and a second conductive layer having a plurality of conductive blocks. The second conductive layer is electrically connected to the first conductive layer over portions where the insulating layer is not formed. A method of controlling lapping depth involves use of the lapping monitor resistor.
