Perpendicular magnetic recording head including nonmagnetic layer overlaying main pole layer

摘要

A perpendicular magnetic recording head includes: an auxiliary pole layer; a main pole layer; a coil layer for providing a recording magnetic field to the auxiliary pole layer and the main pole layer; a nonmagnetic layer; and a connection layer magnetically coupled to the main pole layer. The nonmagnetic layer is formed on the main pole layer to maintain the main pole layer at a predetermined height during manufacture, allowing independent control of the track width Tw and the height of the main pole layer. A method for manufacturing the perpendicular magnetic recording head is also provided.
