Magnetic head for perpendicular magnetic recording including a main pole and a shield
A magnetic head includes a main pole, a write shield, and first and second nonmagnetic layers. The main pole has a top surface including an inclined surface portion. The inclined surface portion includes a first portion and a second portion, the first portion being closer to a medium facing surface. The write shield includes an inclined portion facing toward the top surface of the main pole. The first nonmagnetic layer is interposed between the inclined portion and the second portion of the inclined surface portion. The second nonmagnetic layer is interposed between the inclined portion and a combination of the first portion of the inclined surface portion and the first nonmagnetic layer.
