Thin-film magnetic head comprising shield/magnetic-pole layer having surface without right nor sharp angle
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.
