摘要： A thin-film magnetic head comprises a bottom pole layer having a surface that faces toward a write gap layer. This surface incorporates a first surface including an end portion located in the air bearing surface, and a second surface located away from the air bearing surface. There is a difference in level between the first surface and the second surface, so that the second surface is located farther from the top pole layer than the first surface. A top pole layer incorporates a throat height defining layer, an intermediate layer, and a yoke portion layer. The yoke portion layer includes a track width defining portion for defining the track width. Each of the throat height defining layer, the intermediate layer, and the track width defining portion has a width equal to the track width.

摘要： A thin-film magnetic head comprises a top pole layer incorporating a throat height defining layer and a yoke portion layer. The throat height defining layer is formed as follows. A magnetic layer to be a track width defining portion is formed on a recording gap layer. Next, the magnetic layer is selectively etched through the use of a mask so as to form an end portion of the magnetic layer for defining the throat height. Next, a nonmagnetic layer is formed to fill the etched portion of the magnetic layer while the mask is left unremoved. Next, the yoke portion layer is formed. Using the track width defining portion as a mask, the magnetic layer, the recording gap layer and a portion of the bottom pole layer are etched.

摘要： In a method of manufacturing a thin-film magnetic head, a bottom pole layer is formed and a thin-film coil is formed on the bottom pole layer. A recording gap layer is then formed on the pole portion of the bottom pole layer. Next, the recording gap layer and a portion of the bottom pole layer are selectively etched through the use of a mask so as to form an end portion of the recording gap layer for defining the throat height. Next, a nonmagnetic layer is formed to fill the etched portions of the recording gap layer and the bottom pole layer while the mask is left unremoved. Next, the mask is removed, and the top surfaces of the recording gap layer and the nonmagnetic layer are flattened by polishing. A top pole layer is formed on the flattened top surfaces of the recording gap layer and the nonmagnetic layer.

摘要： The invention is directed to improvement of a write element of a thin film magnetic head. The first pole portion projects from a flat surface of a first yoke portion at a medium-facing surface side and having a reduced width at its upper end. The second pole portion faces the upper end of the first pole portion, having the same width as the upper end of the first pole portion, with the gap film interposed between the second pole portion and the upper end of the first pole portion. The first pole portion includes a magnetic film adjacent to the gap film, the magnetic film etched at both sides in width direction to have a narrowed portion having substantially the same width as the second pole portion, and a base portion connected to the narrowed portion, increasing in thickness toward the narrowed portion.
