<p>A magnetoresistive head reproduces high-density information from a storage medium while suppressing Barkhausen noise. The head comprises a magnetoresistive element consisting of a multilayered film that includes a free magnetic layer where the orientation of magnetization changes depending on the external magnetic field; an insulating layer; a nonmagnetic underlayer formed on the insulating layer; and a pair of wall control layers spaced at a predetermined interval on the underlayer to control the movement of the domain wall of the free magnetic layer. Both ends of the free magnetic layer are attached directly to the pair of domain wall control layers, and the center of the free magnetic layers are attached directly to the underlayer.</p> |
