Magnetic head for perpendicular magnetic recording having a bottom shield including a base part and a protruding part
A magnetic head includes a coil, a main pole, a write shield, and a return path section. The write shield includes a bottom shield located on the rear side in the direction of travel of a recording medium relative to the main pole. The return path section is located on the rear side in the direction of travel of the recording medium relative to the main pole and connects the bottom shield and part of the main pole away from a medium facing surface so as to define a space through which part of the coil passes. The return path section is not exposed in the medium facing surface. The bottom shield includes a base part, and a protruding part protruding from the base part toward the main pole. The base part is greater than the protruding part in length in a direction perpendicular to the medium facing surface.
