Patent ID: 7630172

Claim:
A thin film magnetic head including a substrate and at least an inductive type thin film magnetic head element supported by the substrate; wherein said inductive type thin film magnetic head element comprises; a bottom pole made of a magnetic material which extends inwardly from an air bearing surface; a bottom track pole made of a magnetic material which extends inwardly from the air bearing surface over a distance corresponding to a track pole; a bridge portion made of a magnetic material and formed on one surface of the bottom pole such that a back gap is formed at a position remote from the air bearing surface; a thin film coil formed on the surface of the bottom pole such that a surface of the thin film coil opposite to the bottom pole forms a coplanar flat surface together with a surface of the bottom track pole; a write gap film made of a non-magnetic material and formed on said coplanar flat surface of said bottom track pole and thin film coil to have a flat surface; and a top pole formed on a surface of the write gap film opposite to the bottom track pole and including a top track pole aligned with the bottom track pole, said top pole being brought into contact with the bridge portion; 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, at least a part of each of the coil windings of the second thin film coil half having a two-layer structure consisting of a first conductive film formed by CVD and a second conductive film formed by electrolytic plating; an insulating film formed to embed spaces between successive coil windings of the first and second thin film coil halves; a first 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; and a second jumper wiring having one end connected to an innermost coil winding of the other of the first and second thin film coil halves.
