Patent ID: 7948709

Claim:
A thin-film magnetic head comprising a lower magnetic pole layer exposing an end part on a side of a medium-opposing surface opposing a recording medium, an upper magnetic pole layer opposing the end part of the lower magnetic pole layer such as to form a recording gap at one end part on the side of the medium-opposing surface and connecting with the lower magnetic pole layer at the other end part on a side remote from the medium-opposing surface, and a thin-film coil constituted by a lead wound about the other end part of the upper magnetic pole layer; the lower magnetic pole layer, the upper magnetic pole layer and the thin-film coil being laminated; wherein an organic insulating material made of an electrically insulating organic matter is interposed between turns adjacent to each other in the lead constituting the thin-film coil; wherein the lead constituting the thin-film coil has a minimum width part having the smallest width in the laminating direction and a maximum width part having the largest width in the laminating direction; wherein the minimum width part of the lead is arranged closer to the medium-opposing surface than is the other end part of the upper magnetic pole layer; wherein the maximum width part of the lead is arranged farther from the medium-opposing surface than is the other end part of the upper magnetic pole layer; wherein the upper face of the minimum width part of the lead in the laminating direction is totally covered with the organic insulating material; and wherein the upper face of the maximum width part of the lead in the laminating direction is formed with an uncoated area free of the organic insulating material, the uncoated area being covered with an inorganic insulating material, wherein the lead constituting the thin-film coil further comprises lead conductors that are integrally formed with respective end parts of the lead constituting the thin-film coil and are separate from the minimum width part and the maximum width part.
