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.

摘要： An asymmetric perpendicular magnetic recording head and a method of manufacturing the same, wherein the perpendicular magnetic recording head includes a read head for reading data from a magnetic recording layer and a write head for writing data on the magnetic recording layer. A main pole of the write head has a first surface facing toward the inside of the magnetic recording layer, a second surface opposing a data recording surface of the magnetic recording layer, and a third surface facing toward the outside of the magnetic recording layer and the first surface is asymmetric to the third surface. An angle between one of the first and third surfaces and the second surface may be greater than 90°.
