ABSTRACT:
A method of manufacturing a thin-film magnetic head including forming the first shield layer; forming the magnetoresistive device, carried out after forming the first shield layer, a heat treatment providing exchange coupling between the ferromagnetic layer and the antiferromagnetic layer so as to magnetize the ferromagnetic layer in a predetermined direction; forming the domain control layer so as to hold the magnetoresistive device in a track width direction; magnetizing the domain control layer in a direction yielding a magnetic field in the same direction as with a magnetic field received by the ferromagnetic layer upon exchange-coupling with the antiferromagnetic layer, forming the second shield layer, carried out after magnetizing the domain control layer, and remagnetizing the domain control layer in a direction yielding the longitudinal bias magnetic field, carried out after forming the second shield layer.
