Abstract

A magnetoresistive head includes a first ferromagnetic layer and a non-magnetic material layer adjacent to a center portion of the first ferromagnetic layer. A second ferromagnetic layer is provided adjacent to the non-magnetic metal layer. An anti-ferromagnetic layer covers the second ferromagnetic layer and the first ferromagnetic layer. The anti-ferromagnetic layer is non-planar at an area adjacent to the non-magnetic metal layer and the second ferromagnetic layer. A pair of electrodes is provided adjacent to the two edges of the anti-ferromagnetic layer.
