Abstract:
1. A vertical-current-type reproducing magnetic head, comprising: a sensor film; an upper magnetic-material shield paired with a lower magnetic-material shield that together flow a current into the sensor film in a thickness direction of the sensor film; and magnetic-domain control magnetic films comprising first insulating films provided above both sides of the sensor film in a track width direction of the sensor film, wherein the upper magnetic-material shield is formed via a nonmagnetic adhesion layer second insulating films provided outside both outer sides of the magnetic-domain control magnetic films with respect to the sensor film in a track width direction; and third insulating films, each third insulating film being provided above a surface of each of the second insulating films or continuously provided over an area from a surface region on an outer side in a track width direction of each of the magnetic-domain control magnetic films to a surface of the second insulating film, wherein the nonmagnetic adhesion layer is provided above the third insulating film.
