ABSTRACT:
A lower shield layer is formed by being embedded in a first recess formed in an under layer. Accordingly, the distance between the lower shield layer and a slider can be reduced. Also, a second metal layer is formed from above a gap layer covering an electrode extracting layer over above the under layer hindwards therefrom. Accordingly, the second metal layer can be brought closer to the slider side than an upper shield layer. Consequently, the thermal dissipation effects of the thin-film magnetic head can be improved.
