摘要： A thin-film magnetic head structure has a configuration adapted to manufacture a thin-film magnetic head configured such that a main magnetic pole layer including a magnetic pole end part on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the magnetic pole end part so as to form a recording gap layer on the medium-opposing surface side, and a thin-film coil wound about the write shield layer or main magnetic pole layer are laminated. The main magnetic pole layer includes a base magnetic pole part comprising the magnetic pole end part and a base depression distanced farther from the medium-opposing surface than the magnetic pole end part, and an embedded magnetic pole part buried in the base depression and joined to the base magnetic pole part. The thin-film magnetic head structure includes a yoke magnetic pole part joined to the base magnetic pole part and embedded magnetic pole part at a position distanced farther from the medium-opposing surface than the recording gap layer, and an intervening insulative film disposed between the embedded magnetic pole part and yoke magnetic pole part at a position distanced farther from the medium-opposing surface than the recording gap layer.

摘要： A pole layer is disposed in a groove of a pole-layer-encasing layer made of a nonmagnetic material with a nonmagnetic film disposed between the encasing layer and the pole layer. A polishing stopper layer made of a nonmagnetic conductive material is disposed on the top surface of the encasing layer. The polishing stopper layer indicates the level at which polishing for controlling the thickness of the pole layer is stopped. The polishing stopper layer has a penetrating opening, and the edge of the opening is located directly above the edge of the groove located in the top surface of the encasing layer.
