ABSTRACT:
A thin-film magnetic head structure has a configuration adapted to manufacture a thin-film magnetic head configured such that a main magnetic pole layer including a magnetic pole tip on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the magnetic pole tip so as to form a recording gap layer on the medium-opposing surface side, and a thin-film coil wound about the write shield layer or main magnetic pole layer are laminated. The magnetic pole tip of the main magnetic pole layer includes an even width portion having a substantially even width along an extending direction.
