Patent ID: 8064161

Claim:
A perpendicular magnetic recording head comprising: an auxiliary pole; a main pole; a yoke provided in contact with the main pole; a coil wound around a magnetic circuit composed of the auxiliary pole, the main pole and the yoke; a first soft magnetic film provided on both sides of the main pole with a non-magnetic film provided between the first soft magnetic film and the main pole; and a second soft magnetic film provided on a trailing side of the main pole with the non-magnetic film provided between the second soft magnetic film and the main pole, wherein the first and second soft magnetic films are two types of plated magnetic films, one type of the plated magnetic films having respective thicknesses of 0.5 nm to 20 nm and respective body centered cubic lattice crystal structures, the other type of the plated magnetic films having respective thicknesses of 0.5 nm to 20 nm and respective face centered cubic lattice crystal structures, and the two types of plated magnetic films being alternately laminated with four or more layers.
