When manufacturing a thin film magnetic head, a first magnetic pole and a second magnetic pole are magnetically coupled and face each other in a recording-medium-facing surface. A gap layer is in between the first and second magnetic pole. A thin film coil for generating magnetic flux is also included. A first magnetic layer is formed. A first magnetic pole is then formed on the first magnetic layer so as to be magnetically coupled to part of the first magnetic layer. A first insulating layer is formed 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. The gap layer is formed on the first magnetic pole. Then the second magnetic pole is formed on the gap layer longer than the first magnetic pole. The second magnetic layer is formed so as to be magnetically coupled to part of the second magnetic pole.
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:
