摘要： Provided is a thin-film magnetic head in which the concentration of magnetic flux in the shield layer and the magnetic pole layer is suppressed. The thin-film magnetic head comprises a plurality of magnetic layers that have front surfaces reaching a head end surface on the ABS side. Further in this head, at least one of the plurality of magnetic layers has a shape in which: each of edges corresponding to both side surfaces extends so as to spread obliquely rearward with each other from an end of a straight edge in a track width direction corresponding to the front surface; and the front surface reaching the head end surface has a shape in which upper and lower corner portions in each of both end portions in the track width direction form obtuse angles or rounded shapes.

摘要： A thin film magnetic head has a plurality of electrode terminals formed on substantially the same surface as the head formation surface on which magnetic head element is laminated. The plurality of electrode terminals is arranged in an array near and along the second side of the head formation surface that is opposite the first side on the ABS side, from which the functional end of the magnetic head is exposed. The plurality of electrode terminals is formed to include a pad and a protrusion formed along a part of the periphery of the pad.
