Patent ID: 8102622

Claim:
A method of manufacturing a perpendicular magnetic write head, comprising: forming a magnetic layer on a substrate; forming a first nonmagnetic layer and a second nonmagnetic layer in order on the magnetic layer, with different materials; forming a first mask pattern on the second nonmagnetic layer and removing, through a first etching process, the second nonmagnetic layer in a region which is not covered with the first mask pattern, thereby forming a pattern of the second nonmagnetic layer while leaving the first nonmagnetic layer; and removing the first mask pattern, and selectively performing a first milling process on the first nonmagnetic layer and the magnetic layer with the pattern of the second nonmagnetic layer as a mask, so as to remove all of the first nonmagnetic layer in an exposed region which is not covered with the pattern of the second nonmagnetic layer and to dig down the magnetic layer in the exposed region, thereby forming a main magnetic pole layer having an inclined part which is getting thinner with distance from an edge position of the pattern of the second nonmagnetic layer.
