摘要： A method of manufacturing magnetic heads comprises the step of: fabricating a magnetic head substructure by forming components of a plurality of magnetic heads on a single substrate, wherein a plurality of rows of pre-head portions that will be the respective magnetic heads later are aligned in the substructure; and fabricating the magnetic heads by separating the pre-head portions from one another through cutting the substructure. In the substructure first resistor elements and second resistor elements are formed. Each of the first resistor elements has a resistance that varies depending on the location of an end of an MR element located in a medium facing surface along the direction orthogonal to the medium facing surface. Each of the second resistor elements has a resistance that varies depending on the location of an end face of a track width defining portion located in the medium facing surface along the direction orthogonal to the medium facing surface. The medium facing surfaces are formed while monitoring the resistance values of the first and second resistor elements.

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.

摘要： A recording head has a bottom pole layer, a top pole layer, a recording gap layer, and a thin-film coil. The bottom pole layer includes a first portion and a second portion. The first portion is located in a region facing toward the thin-film coil. The second portion is connected to the first portion and defines a throat height. The thin-film coil is located on a side of the second portion. The top pole layer includes a track-width-defining portion. An end of the track-width-defining portion opposite to the air bearing surface is located closer to the air bearing surface than an end of the second portion opposite to the air bearing surface. A portion of the second portion has a width the same as that of the track-width-defining portion.

A shield layer has an end that is located in the medium facing surface and that has an edge on a side of the gap layer. This edge includes: a first portion facing toward the first side, the gap layer being disposed in between; two second portions that are disposed on both sides of the first portion opposed to each other in the direction of the track width and that are disposed such that a difference in level is created between the first portion and each of the second portions; a third portion connecting an end of the first portion to one of the second portions; and a fourth portion connecting the other end of the first portion to the other one of the second portions. Each of the above-mentioned difference in level and the distance between the straight line drawn in line with the second side and the second portions is smaller than the distance between the straight line and the first portion.
