Abstract
A magnetic head comprises a pole layer, a shield layer, a gap layer disposed between the pole layer and the shield layer, and a coil. The shield layer incorporates: a first layer disposed on the gap layer; a second layer disposed on the first layer; and a third layer disposed on the second layer. The first layer has an end face located in a medium facing surface. An end face of each of the second and third layers closer to the medium facing surface is located at a distance from the medium facing surface. A first nonmagnetic layer is disposed around the first layer. A second nonmagnetic layer is disposed between the medium facing surface and the end face of the second layer closer to the medium facing surface.
