Magnetic head for perpendicular magnetic recording having a return path section
A magnetic head includes a main pole and a return path section located above a top surface of a substrate. The main pole has an end face located in a medium facing surface. The return path section is located on the front side in the direction of travel of a recording medium relative to the main pole and is farther from the top surface of the substrate than is the main pole. The return path section has: a front end face located on the front side of the main pole in the medium facing surface; and an inclined surface located on the front side and connected to the front end face. The inclined surface is not exposed in the medium facing surface. An angle greater than 90° is formed between the front end face and the inclined surface.
