Abstract

A single magnetoresistive element ganged MR head sensor. The sensor is comprised of a single magnetoresistive element divided into a plurality of sense regions by more than two electrical contacts, the facing sides of each being parallel to each other and perpendicular to the lower edge of the element. No other transverse biasing is applied and the sensor operates in a non linear mode. The provision of no transverse biasing reduces cross talk.
