摘要： A magnetic write head for perpendicular magnetic recording, the write head having a magnetic write pole configured with a cross section as viewed from the ABS that has a trailing portion with substantially vertical side walls and a leading portion formed with a taper that becomes narrower as it extends toward the leading edge. The write pole provides for excellent write field strength by providing sufficient cross section near the trailing edge to avoid magnetic saturation of the pole tip. The parallel side walls of the trailing portion also provide for excellent track width control during manufacture of the write head. The tapered portion of the write head, which starts some distance away from the trailing edge, prevents skew related adjacent track writing when the actuator that holds the write head is at its innermost or outermost travel extensions.
