Abstract:
A method of manufacturing a thin film magnetic head having at least two magnetic layers including a first magnetic pole and a second magnetic pole being magnetically coupled to each other, part of sides of which facing a recording medium face each other sandwiching a write gap layer, and one or more than two layers of thin film coil for generating magnetic flux, including the steps of:forming a first magnetic pole on the first magnetic layer so as to be magnetically coupled to part of a region of the first magnetic layer after forming the first magnetic layer; forming insulating layers of inorganic materials extendedly, at least from a surface of the first magnetic pole which is the opposite side of a surface facing the recording medium to one of the surfaces of the first magnetic layer; forming a thin film coil within a concave region in which the insulating layers are formed; forming the second magnetic pole to be longer than the first magnetic pole so as to face at least a part of thin film coil to the inner direction from a surface facing the recording medium at least sequentially after forming a write gap layer on the first magnetic pole; and forming the second magnetic layer in direct contact with the second magnetic pole.
