| 1. A thin film magnetic head comprising:
first and second magnetic layers magnetically coupled to each other and having first and second pole tip portions placed so
as to face a recording medium in conjunction with being in contact with a gap layer and being opposed to each other as sandwiching
the gap layer, wherein the first and second magnetic layers have substantially the same thickness;
a thin film coil disposed in a space between the first and second magnetic layers; and
an insulating layer embedding the thin film coil in the space between the first and second magnetic layers, wherein:
the first pole tip and the first magnetic layer are formed as a plated film on the gap layer; and
the gap layer is constructed of a non-magnetic conductive material extends from the pole tip over the thin film coil.
