A wire gap film is formed on a flat coplanar surface formed on a bottom pole by a bottom track pole and a thin film coil, first and second magnetic material films constituting a top pole are formed on a flat surface of the thin film coil, and the first and second magnetic material films, write gap film and bottom track pole are partially removed forming a top track pole and trim structure. The thin film coil is formed by first and second thin film coil halves having self-aligned coil windings and have a CVD formed first conductive film, and an electrolytic plating formed second conductive film. A thin insulating film is interposed between successive coil windings of the first and second thin film coil halves. Jumper wirings, formed with the top pole, connect innermost and outermost coil windings of the first and second thin film coil halves respectively.
