发明名称 Method of manufacturing magnetic head for perpendicular magnetic recording
摘要 A main pole layer of a magnetic head includes a first portion disposed at a distance from a medium facing surface, and a second portion that is smaller in thickness than the first portion and disposed between the first portion and the medium facing surface. The step of forming the main pole layer includes the steps of forming a plating layer such that one of ends of the plating layer closer to the medium facing surface is located at a position that coincides with the position of one of ends of the first portion closer to the medium facing surface; forming a first nonmagnetic layer to cover the plating layer; polishing the first nonmagnetic layer and the plating layer; forming a space by removing the plating layer; forming a magnetic layer, which will be the main pole layer, in the space and on the top surface of the first nonmagnetic layer; forming a second nonmagnetic layer to cover the magnetic layer; and polishing the second nonmagnetic layer and the magnetic layer.
