Abstract:
1. A perpendicular magnetic recording head for one of recording and reading information on or from a perpendicular magnetic recording medium, the perpendicular magnetic recording head comprising: a coil serving as a source generating a magnetic field for recording; a main pole forming a magnetic path of the magnetic field, having an end that faces the perpendicular magnetic recording medium, wherein the end comprises a leading part serving as a front side and a trailing part serving as a rear side with respect to a movement direction of the perpendicular magnetic recording medium; the trailing part having edges that are chamfered; and the leading part having a plane inclined with respect to an air-bearing surface (ABS); and a return pole forming the magnetic path of the magnetic field in cooperation with the main pole, and having one end spaced apart from the main pole at the ABS and the other end connected with the main pole, wherein a plane of the main pole that faces the perpendicular magnetic recording medium has a hexagon shape.
