摘要： Provided is a vertical writing type magnetic head including a substrate, a bottom pole formed on the substrate, and a top pole aligned with and spaced a predetermined distance apart from the bottom pole, wherein the bottom pole has a narrower width than the top pole. The magnetic write head is constructed such that the width of a bottom pole is narrower than that of a top pole, thereby reducing extension of a magnetic field at sides of a top pole and effectively preventing erasure of information of an adjacent track due to the bottom pole overlapping the adjacent track when there is a constructional skew in a hard disk drive.

摘要： A perpendicular magnetic recording head and method of manufacturing the same are provided. The perpendicular magnetic recording head records or reads information on or from a perpendicular magnetic recording medium. The perpendicular magnetic recoding head includes a coil, a main pole, and a return pole. The coil serves as a source for generating a magnetic field. The main pole and the return pole constitute a magnetic path of the magnetic field. The main pole includes an end facing the perpendicular magnetic recording medium. The end includes 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. Both edges of the trailing part are chamfered, and the leading part has a plane inclined with respect to an air-bearing surface (ABS). The return pole has an end spaced from the main pole, and the other end connected with the main pole.
