    摘要： A method of taper-etching a layer to be etched that is made of a dielectric material and has a top surface. The method includes the steps of: forming an etching mask with an opening on the top surface of the layer to be etched; and taper-etching a portion of the layer to be etched, the portion being exposed from the opening, by reactive ion etching so that a groove having two wall faces intersecting at a predetermined angle is formed in the layer to be etched. The step of taper-etching employs an etching gas containing a first gas contributing to the etching of the layer to be etched and a second gas contributing to the deposition of a sidewall protective film, and changes, during the step, the ratio of the flow rate of the second gas to the flow rate of the first gas so that the ratio increases.

    摘要： A magnetic head includes a main pole, a return path section, a heater for heating the main pole, and a metal portion. The metal portion is isolated from the return path section and disposed such that the heater is interposed between the main pole and the metal portion. The return path section has a contact surface in contact with the main pole. The metal portion is located farther from the medium facing surface than is the contact surface. The main pole and the metal portion define therebetween a receiving space for receiving at least part of the heater. The at least part of the heater is received in the receiving space.

    摘要： A thin-film magnetic head includes a main magnetic pole layer, write shield layer, gap layer, and thin-film coils, which are laminated on a substrate. A return magnetic pole layer is spaced from the medium-opposing surface on the side opposite to the write shield layer with the main magnetic pole layer intervening therebetween. A connecting magnetic layer is formed using a magnetic material to connect the return magnetic pole layer to the write shield layer on the side closer to the medium-opposing surface than is the thin-film coil. The thin-film coil is wound as a flat spiral around the write shield layer. A part of the thin-film coil wound as the flat spiral is disposed only at a position distanced from the substrate than is the main magnetic pole layer.

    摘要： A magnetic head includes first and second coils, a main pole, a write shield, a return path section, and a core part. The return path section includes a yoke part magnetically connected to the write shield, and a coupling part located away from a medium facing surface and magnetically coupling the yoke part and the main pole to each other. The first coil is located on the front side in the direction of travel of a recording medium relative to the main pole and wound around the coupling part. The core part is located farther from the medium facing surface than is the coupling part, and is magnetically connected to the main pole. The second coil is located on the front side in the direction of travel of the recording medium relative to the main pole and wound around the core part.
