Abstract:
A thin film magnetic head comprising:a first magnetic member made of a magnetic material and including a pole portion which is to be opposed to a magnetic record medium; a second magnetic member made of a magnetic material and including a pole portion which constitutes an air bearing surface together with an end surface of the pole portion of the first magnetic member, said second magnetic member being magnetically coupled with said first magnetic member at a back gap remote from the air bearing surface; a write gap film made of a non-magnetic material and being sandwiched between said pole portions of the first and second magnetic members at least at the air bearing surface; a thin film coil having a portion arranged between said first and second magnetic members in an electrically isolated manner; and a substrate for supporting said first and second magnetic members, write gap film and thin film coil; wherein said thin film coil comprises: a first thin film coil half having coil windings mutually separated by a given distance; a second thin film coil half having coil windings which are formed between successive coil windings of the first thin film coil half in a self-aligned manner; an insulating film formed to embed spaces between successive coil windings of the first and second thin film coil halves; and a jumper wiring connecting electrically an innermost coil winding of one of the first and second thin film coil halves to an outermost coil winding of the other of the first and second thin film coil halves, said first magnetic member is formed by a first pole, said second magnetic member is formed by a track pole which is opposed to said pole portion of the first magnetic member via the write gap film and a second pole having one end magnetically coupled with the track pole and the other end magnetically coupled with the first pole at the back gap, and said jumper wiring is made of a same material as that of the second pole of the second magnetic member and is formed simultaneously with the second pole.
