Vertical-current-type reproducing magnetic head and method of manufacturing the same
Abstract:
In one embodiment, a vertical-current-type reproducing magnetic head includes a sensor film, an upper shield paired with a lower shield that together flow a current into the sensor film in a thickness direction of the sensor film, and magnetic-domain control magnetic films provided above both sides of the sensor film in a track width direction of the sensor film. The shield is formed via a nonmagnetic adhesion layer including a discontinuous region near the sensor film, and the sensor film contacts the upper shield. In another embodiment, a method includes forming a resist layer, etching a sensor film while using the resist layer as a mask, forming first insulating films, domain-control magnetic films, and nonmagnetic adhesion layers in a stacked manner, lifting-off the resist layer, and forming an upper shield that together with a lower shield flow current into the sensor film in a thickness direction of the sensor film.
