摘要： Provided is a bit patterned medium including bridges which induce exchange coupling between adjacent bits in order to reduce a switching field difference resulting from different magnetization directions of bits. The bridges and the bits are integrally formed with each other. The bits are locally connected by the bridges. A magnetostatic force for each bit is reduced due to an exchange coupling between adjacent bits, thereby reducing a switching field distribution of the bits.

摘要： A perpendicular magnetic recording medium including a soft magnetic underlayer. The perpendicular magnetic recording medium includes: a lower structural body including an anti-ferromagnetic layer; a first soft magnetic underlayer, a non-magnetic layer, and a second soft magnetic underlayer sequentially formed on the anti-ferromagnetic layer, where the thickness ratio of the second soft magnetic underlayer to that of the first soft magnetic underlayer is designed to be within specific range; and a recording layer formed on the second soft magnetic underlayer. Therefore, noise generated on the soft magnetic underlayer due to external magnetic fields of a magnetic head and a voice coil motor can be reduced greatly.

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.
