摘要：
A magnetic head includes: a pole layer; a nonmagnetic layer disposed on part of the top surface of the pole layer; a gap layer disposed on the pole layer and the nonmagnetic layer; and a shield disposed on the gap layer. The top surface of the pole layer includes: a first portion having a first edge located in a medium facing surface and a second edge opposite thereto; and a second portion located farther from the medium facing surface than the first portion and connected to the first portion at the second edge. The first portion is inclined with respect to a direction orthogonal to the medium facing surface so that the distance from a substrate increases with increasing distance from the medium facing surface. The nonmagnetic layer has a bottom surface touching the second portion, and this bottom surface has an edge located at the second edge.
