Perpendicular Magnetic Recording Head and Perpendicular Magnetic Recording/Reproducing Head

摘要

A perpendicular magnetic recording head according to the present invention is composed of a first magnetic layer having a main magnetic pole exposed at a facing surface opposite a recording medium, a second magnetic layer adjacent to the first magnetic layer with an intermediary non-magnetic layer disposed therebetween, and a coil layer for applying a recording magnetic field to the first magnetic layer. Since the second magnetic layer has a shape including a substantially arched portion in its cross section along a height direction, it becomes possible to keep an Edge Write magnetic field in a low level and improve external magnetic field resistance.
