ABSTRACT:
In a non-magnetic material layer, a concave portion is formed above a groove G. In addition, an auxiliary magnetic pole layer is formed having a convex portion which extends in the direction toward a main magnetic pole layer and which is placed in the concave portion. Accordingly, since a magnetic flux B passing in a perpendicular magnetic recording head from the main magnetic pole layer to the auxiliary magnetic pole layer is generated, an appropriate adjustment of the intensity of a magnetic field A generated from the main magnetic pole layer can be easily performed, and the edge of a recording track on a recording medium M can be clearly defined.
