A magnetoresistive sensor having an MR stack biased by high anisotropy
hard bias elements thereby reducing distortion in sensor operation and
improving head to head operational values. The high anisotropy hard bias
elements are formed from a hard magnetic material deposited in a thin
film having a substantially axial preferred direction of magnetic
anisotropy prior to application of a setting field. The magnetic
anisotropy in the hard magnetic material is formed by oblique deposition
in a direction approximately normal to the preferred direction of
anisotropy in the resulting hard bias element.
