Patent ID: 6885519

Claim:
A thin film magnetic head including: a first magnetic layer and a second magnetic layer which are magnetically coupled to each other and have two magnetic poles facing each other with a gap layer in between near and in a recording-medium-facing surface to be faced with a recording medium; and a thin film coil provided between the first and second magnetic layers with an insulating layer in between, the first magnetic layer having a predetermined magnetic layer portion including a uniform width portion which extends away from the recording-medium-facing surface and determines a write track width on the recording medium, wherein the predetermined magnetic layer portion includes a first magnetic film and a second magnetic film which are located apart from and close to the gap layer, respectively, and both the first and second magnetic films are made of a magnetic material having a magnetic flux density of 1.5 tesla or more, and wherein a first nonmagnetic layer pattern, which extends in such a manner that the rearward portion thereof is coupled to the insulating layer and the front edge thereof terminates at a predetermined position at the front of the recording-medium-facing surface, is provided between the second magnetic layer and the second magnetic film.
