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.
