ABSTRACT:
A thin-film magnetic head for perpendicular magnetic recording includes a nonmagnetic conductive elevation layer disposed under a main magnetic pole layer. The nonmagnetic conductive elevation layer and the main magnetic pole layer forms a trapezoidal shape converging toward an auxiliary magnetic pole layer, viewed from a face opposing a recording medium. The thin-film magnetic head for perpendicular magnetic recording includes an auxiliary magnetic pole layer, the main magnetic pole layer, and a nonmagnetic insulating layer disposed therebetween at a surface facing the recording medium.
