ABSTRACT:
The ends of lead conductor layers, which ends mark the boundaries of a signal detection area are made substantially perpendicular in the vicinity of a magnetoresistance element, and are sloped in the vicinity of an upper shield so that the lead conductor layers are thicker away from the signal detection area; a recording gap is a regularly shaped gap at least over a spatial range corresponding to a signal detection area.
