Abstract:
1. A magnetic head comprising: an upper magnetic shield; a lower magnetic shield; and a magnetoresistive film formed between the upper magnetic shield and the lower magnetic shield; wherein the magnetoresistive film has a domain control layer including an antiferromagnetic layer, a longitudinal biasing layer and a non magnetic separation layer, a first ferromagnetic layer whose magnetization direction is changed by an external magnetic field, a non-magnetic layer, and a second ferromagnetic layer whose magnetization direction is fixed; and wherein a pair of side magnetic shields, each of which is a multi-layered film including a plurality of soft magnetic layers and a plurality of separate layers arranged alternately, are formed on both sides in a track width direction of the magnetoresistive film and converge along a line formed by an upper corner of the magnetoresistive film and the upper magnetic shield.
