ABSTRACT:
Both hard and easy axis bias fields are applied to the sense film of an unshielded magnetoresistive (UMR) magnetic head by a single bias source. The easy and hard axis fields are applied to the UMR sense film by so angling the applied bias field that orthogonal components of the field lie, respectively, in the directions of the easy and hard axes of the film.
