ABSTRACT:
A thin-film magnetic head is constructed such that a main magnetic pole layer having a magnetic pole end face on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the main magnetic pole layer on the medium-opposing surface side, a gap layer formed between the main magnetic pole layer and write shield layer, and a thin-film coil wound about the write shield layer or main magnetic pole layer are laminated on a substrate. This thin-film magnetic head has an equidistant two-stage structure in which a first turn part of a first conductor layer and a second turn part of a second conductor layer overlap vertically along the medium-opposing surface while having the same front distance from respective front side faces closer to the medium-opposing surface to the medium-opposing surface.
