Abstract:
A method of manufacturing a thin film magnetic head including a first magnetic pole and a second magnetic pole that are magnetically coupled to each other and face each other with a gap layer in between, in a recording-medium-facing surface and a thin film coil for generating magnetic flux, the method comprising the steps of:forming a first magnetic layer and then forming the first magnetic pole on the first magnetic layer so as to be magnetically coupled to part of the first magnetic layer; forming a first insulating layer with an inorganic material extendedly from a surface of the first magnetic pole opposite to the recording-medium-facing surface to a top surface of the first magnetic layer; forming the gap layer on the first magnetic pole and then forming on the gap layer the second magnetic pole longer than the first magnetic pole, and forming a second magnetic layer so as to be magnetically coupled to part of the second magnetic pole.
