ABSTRACT:
A magnetoresistive sensor has a high resistance soft magnetic layer disposed between the sensor stack and at least one magnetic shield. The presence of the high resistance soft magnetic layer allows a smaller magnetic read gap to be achieved which results in higher recording density. The susceptibility of the magnetoresistive sensor to defects and electrostatic damage is improved. A disk drive is provided having the novel magnetoresistive sensor.
