ABSTRACT:
A manufacturing method in which a second magnetic layer of a thin-film magnetic head includes the steps of: forming a pole portion layer; forming a protective layer so as to cover a part of the pole portion layer located near the medium facing surface ABS; forming an electrode layer to be used as an electrode when forming a yoke portion layer by electroplating; forming the yoke portion layer by electroplating on the electrode layer using the electrode layer as an electrode; and removing an unnecessary portion of the electrode layer.
