The present invention provides a thin film magnetic head in which a first coil
layer is formed at the back of a track width control portion. The first coil layer
being location nearer a bottom core layer than the junction surface of a track
width control portion and an upper core layer. With a two-layer structure, the
width of the coil layer can be decreased. The height from the top of the bottom
core layer to the top of an insulating layer can be decreased. The insulating layer
covering a second coil layer can be decreased, thereby shortening the magnetic
path and decreasing inductance.
