摘要：
A method of manufacturing a perpendicular magnetic recording head capable of easily and accurately forming a main magnetic-pole layer having a shape suitable for concentrating a magnetic flux is provided. A nonmagnetic layer having a recessed section (a first recessed section and a second recessed section) is formed, and then an additional nonmagnetic layer is formed on an inner surface of the recessed section. Then, a magnetic layer is formed in the recessed section formed with the additional nonmagnetic layer, and then the magnetic layer is cut to form an air bearing surface, so as to form the main magnetic-pole layer.
