摘要：
A thin-film magnetic head includes a lower electrode layer, an MR multi-layered structure, through which a current passes in a direction perpendicular to a lamination plane, stacked on the lower electrode layer, soft magnetic layers for magnetic domain control formed on both sides in a track width direction of the MR multi-layered structure, an anti-ferromagnetic layer for magnetic domain control continuously stacked on the MR multi-layered structure and the soft magnetic layers for magnetic domain control, the anti-ferromagnetic layer mutually exchanged-coupled to the soft magnetic layers for magnetic domain control, and an upper electrode layer stacked on the anti-ferromagnetic layer for magnetic domain control.
