摘要 |
A thin-film magnetic head has a laminated construction comprising a main pole layer having a magnetic pole tip on the side of the medium-opposing surface opposing a recording medium, a write shield layer opposite the magnetic pole tip forming a recording gap layer, on the side of the medium-opposing surface, and a thin-film coil wound around at least a portion of the write shield layer. The main pole layer has the magnetic pole tip with a shortened structure which is not connected to the write shield layer, and an upper yoke pole section and/or lower yoke pole section with a larger size than the magnetic pole tip, and has a joined structure wherein the upper yoke pole section and/or lower yoke pole section is joined to the magnetic pole tip.
