Abstract
A pole layer has an end face located in a medium facing surface, allows a magnetic flux corresponding to a magnetic field generated by a coil to pass therethrough, and generates a write magnetic field. A shield includes a first layer having an end face located in the medium facing surface at a position forward of the end face of the pole layer along a direction of travel of a recording medium, and a second layer disposed between at least part of the coil and the medium facing surface and magnetically connected to the first layer. The second layer has an end face closer to the medium facing surface, and this end face is located at a distance from the medium facing surface. A nonmagnetic layer made of an inorganic insulating material is provided between the end face of the second layer and the medium facing surface, and a photoresist layer is provided between the end face of the second layer and the nonmagnetic layer.
