Patent ID: 8358487

Claim:
A thin-film magnetic head 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 around any of the main magnetic pole layer, the write shield layer or a shield magnetic layer connected the main magnetic pole layer are laminated on a substrate; wherein the thin-film coil has a coil-layer having a turn part arranged at a position closer to the medium-opposing surface than is a rear end part of the main magnetic pole layer farthest from the medium-opposing surface, and wherein supposing that the thickness of the coil-layer in a direction along the medium-opposing surface is a coil thickness and a part of the coil-layer corresponding to an arrangement space where the main magnetic pole layer is arranged is a magnetic pole corresponding part, the thin-film coil is formed such that, at least in a substrate side coil-layer arranged between the main magnetic pole layer and the substrate in the coil-layer, the coil thickness of a non-corresponding magnetic pole part that is a part other than the magnetic pole corresponding part is larger than the coil thickness of the magnetic pole corresponding part.
