Patent ID: 8353098

Claim:
A method of manufacturing a perpendicular magnetic recording head, the method comprising; forming a nonmagnetic layer having a first recessed section and a second recessed section coupled with a rear part of the first recessed section, the first recessed section including a width which is constant in a le direction and a width which becomes gradually narrower in a depth direction and the second recessed section including a width which becomes gradually wider in the length direction and a width which becomes gradually narrower in the depth direction, the length direction being a direction going rearward from an air bearing surface, and the depth direction being a direction going toward a leading side from a trailing side; forming an additional nonmagnetic layer on an inner surface of the first and the second recessed sections; forming a magnetic layer in the first and the second recessed sections which are formed with the additional nonmagnetic layer; and forming a main magnetic-pole layer by cutting the magnetic layer and thereby forming the air bearing surface, wherein, in the first and the second recessed sections which are formed with the additional nonmagnetic layer, a depth of the first recessed section is made shallower than a depth of the second recessed section, and the depth of the second recessed section is made gradually shallower as approaching the first recessed section on a side close to the first recessed section.
