摘要： According to one embodiment, a magnetic recording head includes a spin-torque oscillator between a main pole and a trailing shield. An oscillation layer of the spin-torque oscillator is formed by repeatedly stacking two or more laminates each including a metallic magnetic layer of a body-centered cubic crystalline metal and a metallic magnetic layer containing cobalt. The film thickness of each metallic magnetic layer is more than 0.2 nm and not more than 3 nm. The intensity of an anisotropic magnetic field is higher than a value obtained by subtracting the intensity of a gap magnetic field from the intensity of a diamagnetic field and lower than the intensity of the diamagnetic field.

摘要： A system and method for magnetic transfer. A magnetic transfer device includes a plurality of pairs of magnetic field generating units that apply a magnetic field to a contact body which includes a master disk in close contact with a magnetic recording medium, wherein the master disk has a pattern of preformatted signals. The magnetic field generating units, falling within a specified length range, are moved in synchrony at a predetermined speed in the directions of the outer periphery while the contact body is caused to rotate by a rotation drive unit. The system and method provide a magnetic transfer method and a magnetic transfer device that, by reducing the area of magnetic field generating units that apply a transfer magnetic field, can reduce an attractive force (or repulsive force) between the magnets, and furthermore, shorten a processing time for the transfer.
