Abstract:
A magnetoresistive head having a first and a second ferromagnetic layer separated by a nonmagnetic conductive layer or a nonmagnetic tunneling barrier layer; a magnetoresistive film in which the magnetization direction of the first ferromagnetic layer is fixed by a first antiferromagnetic layer provided to be contacted with the first ferromagnetic layer opposite to said nonmagnetic conductive layer or said nonmagnetic tunneling barrier layer; and a pair of electrodes for flowing a sense current to the magnetoresistive film, wherein a second antiferromagnetic layer is formed to be contacted with said second ferromagnetic layer opposite to said nonmagnetic conductive layer or said nonmagnetic tunneling barrier layer, and a hard magnetic film is formed at each edge of said magnetoresistive film in the track width direction.
