Patent ID: 7397632

Claim:
A single magnetic pole head for vertical magnetic recording, comprising: a main magnetic pole; a return yoke; an insulating layer being formed between said main magnetic pole and said return yoke; a coil being formed in said insulating layer; a nonmagnetic electric conductive layer, which is made of Ru, Rh, Pt, Pd, Au or an alloy thereof, being formed on a front end of said main magnetic pole, which faces a surface of a recording medium; and a trailing shield being formed at a front end of said return yoke, which faces the surface of the recording medium, wherein at least one of said main magnetic pole and said trailing shield is a soft magnetic film, which is formed, by electrolytic plating, on said nonmagnetic electric conductive layer, the soft magnetic film is made of FeCo, whose composition is indicated as FexCo1-x (60≦x≦75 wt %), the FeCo film has a bcc crystal structure, and the crystal of the FeCo film is oriented to a crystal face of ( 110 ).
