Magnetic head for perpendicular recording having a plurality of magnetic path portions
A magnetic head includes a coil, a main pole, a write shield, and a return path section. The return path section includes a yoke layer located on the front side in the direction of travel of a recording medium relative to the main pole, and a coupling part coupling the main pole and the yoke layer to each other. The coupling part includes a plurality of magnetic path portions that separate a magnetic flux into a plurality of fluxes and allow the fluxes to pass therethrough in parallel. The coil includes a plurality of winding portions disposed around the plurality of magnetic path portions, respectively.
