Patent ID: 6971156

Claim:
A method of manufacturing a thin film magnetic head including two magnetic layers magnetically coupled to each other, and having two magnetic poles which face each other with a gap layer in between, and face a recording medium, a thin film coil including a first hierarchical pattern and a second hierarchical pattern, and an insulating layer for insulating the thin film coil from the two magnetic layers, the method comprising: a first step of forming a first precursory layer made from a group of materials consisting of copper, gold and aluminum as a preparatory layer of the first hierarchical pattern of the thin film; a second step of forming a separate precursory layer made of an insulating material on the first precursory layer; a third step of forming a second precursory layer as a preparatory layer of the second hierarchical pattern on the separate precursory layer; and a fourth step of continuously patterning the second precursory layer, the separate precursory layer and the first precursory layer to selectively form the second hierarchical pattern, a separate layer and the first hierarchical pattern, in a batch process, the separate layer electrically isolating the first hierarchical pattern from the second hierarchical pattern.
