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： Provided is a perpendicular magnetic recording medium. The perpendicular magnetic recording medium includes: a lower structure; and a recording layer formed on the lower structure, wherein the recording layer has a balancing force 2πMr2/K1 of 0.5 or less and a factor 4πMr/Hc of 0.8 or less where Mr denotes a remnant magnetization, K1 denotes a perpendicular magnetic anisotropy energy constant, and Hc denotes a coercive force. Accordingly, even though grain boundaries between grains that constitute the recording layer are somewhat non-uniform in width, the grains can have almost the same nucleation field. As a result, the perpendicular magnetic recording medium can ensure high recording density and stability of recorded information.

摘要： A recording medium including a perpendicular magnetic recording layer and a laminated SUL formed on a substrate is provided. The SUL includes an antiferromagnetic layer interposed between laminated structures including a magnetic layer, a non-magnetic layer and a magnetic layer. The layers may each have a thickness of 20 nm or less and the layers below the antiferromagnetic layer may be thinner than the layers on the antiferromagnetic layer. The laminated structures formed on and below the antiferromagnetic layer have unidirectional magnetic anisotropies set in the opposite radial direction to each other by an exchange bias. As a result, media magnetic domain noise can be diminished.
