Magnetic head for perpendicular magnetic recording having a return path section
Abstract:
A magnetic head includes a coil, a main pole, and a return path section. The return path section 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 winding portion disposed around an assemblage of the plurality of magnetic path portions. In any cross section that intersects all of the plurality of magnetic path portions, the distance between two adjacent magnetic path portions is smaller than the minimum width of each of the two adjacent magnetic path portions, and only a nonmagnetic layer is present between the two adjacent magnetic path portions.
