ABSTRACT:
A thin-film magnetic head comprises a top pole layer incorporating a throat height defining layer, an intermediate layer, and a yoke portion layer. The yoke portion layer includes a track width defining portion for defining the track width. Each of the throat height defining layer, the intermediate layer, and the track width defining portion has a width equal to the track width. The length of the intermediate layer is greater than the length of the throat height defining layer, and the length of the yoke portion layer is greater than the length of the intermediate layer, each of the lengths being taken in the direction orthogonal to the air bearing surface.
