Abstract
A magnetoresistive (MR) read transducer comprising an MR layer having longitudinally magnetized end regions separated by a central active region and a soft magnetic biasing layer parallel to but spaced from the MR layer. The easy axes of the MR layer and the soft magnetic biasing layer are tilted at a small angle with respect to the longitudinal axis of the transducer and these angles are substantially equal, but in the opposite sense.
