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.
