Patent ID: 8107193

Claim:
A perpendicular magnetic recording head, comprising: a main magnetic pole, comprising: a write magnetic pole layer for recording, the write magnetic pole layer comprising magnetic layers being antiferromagnetically coupled via a thin non-magnetic conductor layer between the magnetic layers, wherein the write magnetic pole layer for recording has a flare section which gradually widens toward a top of the main magnetic pole in a height wise direction of a throat height section; a non-magnetic cap layer laminated above an uppermost layer of the write magnetic pole layer, the non-magnetic cap layer being textured to provide anisotropy; and a subsidiary magnetic pole layer for supplementing the recording laminated above the non-magnetic cap layer; an auxiliary magnetic pole; a magnetic shield positioned via a non-magnetic layer on a trailing edge of the main magnetic pole and on both sides of the main magnetic pole in a track width direction; and a coil for generating a recording magnetic field.
