ABSTRACT:
A thin-film magnetic head for perpendicular magnetic recording comprises a coil, a main magnetic pole layer for performing perpendicular recording, a write shield layer and a write gap layer, wherein the main magnetic pole layer comprises a main pole film portion and a yoke pole film portion. The write shield layer has a first shield film portion for determining a throat height, and the thickness of the first shield layer is smaller than the thickness of the yoke pole film portion.
