Patent ID: 7990654

Claim:
A perpendicular magnetic recording head, comprising: a main magnetic pole layer; and an auxiliary yoke layer that overlaps the main magnetic pole layer as viewed in a top view and is magnetically coupled to the main magnetic pole layer, the main magnetic pole layer including: a pole straight part exposed to an opposing surface opposite a recording medium, and a flared part that extends from the pole straight part in a height direction, the flared part broadening in a track width direction as the flared part extends in the height direction, wherein the auxiliary yoke layer includes a flared part that extends from the recording medium-opposing surface, the flared part broadening in the track width direction as the flared part extends in the height direction, wherein the flared part of the auxiliary yoke layer is disposed at a position located closer to the rear side in the height direction than the flared part of the main magnetic pole layer, wherein the flared part of the main magnetic pole layer is formed at a flare angle greater than a flare angle of the auxiliary yoke layer, wherein the flared part of the main magnetic pole layer has a first flared part that is disposed between the pole straight part and a second flared part, the first flared part broadens in the track width direction at a first flare angle as the first flared part extends in the height direction, the second flared part broadens in the track width direction at a second flare angle as the second flared part extends in the height direction, and wherein the second flare angle is designed so as to be greater than the flare angle of the auxiliary yoke layer.
