摘要:
A magnetic head includes a coil, a main pole and a return path section. The return path section is located on the trailing side relative to the main pole so that a space is defined between the main pole and itself. The coil includes a first winding portion and a second winding portion connected in series. The first winding portion extends to pass through the aforementioned space, and extends once around the entire perimeter of the main pole as viewed from the medium facing surface. The second winding portion does not pass through the aforementioned space, and surrounds only a part of the entire perimeter of the main pole as viewed from the medium facing surface.
