Patent ID: 7580222

Claim:
A thin-film magnetic head having a laminated construction comprising a main pole layer having a magnetic pole tip on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing said magnetic pole tip forming a recording gap layer, on the side of said medium-opposing surface, and a thin-film coil wound around at least a portion of said write shield layer, wherein said main pole layer comprises said magnetic pole tip with a shortened structure which is not connected to said write shield layer, and a yoke pole section away from said medium-opposing surface with a larger size than said magnetic pole tip, and comprises a joined structure wherein said yoke pole section is flat and is joined to a section at the side away from the medium-opposing surface excluding the side of the medium-opposing surface of said magnetic pole tip, and an insulating film layer disposed between said magnetic pole tip and the thin-film coil, the insulating film layer being laminated between said yoke pole section and the thin-film coil, a section at the side of the medium-opposing surface of the thin-film coil being laminated on said magnetic pole tip, and the insulating film of the insulating film layer having uniform thickness.
