Patent ID: 6982845

Claim:
A magnetic recording apparatus, comprising: a magnetic field impression unit that impresses a magnetic field to a magnetic recording medium; a current supplying unit that supplies a current to the magnetic recording medium; and a controlling unit that makes the current supplying unit supply the current to the magnetic recording medium while making the magnetic field impression unit impress the magnetic field to at least a unit of a magnetic recording unit of the magnetic recording medium, to thereby record information magnetically by making a direction of a magnetization of the magnetic recording unit of the magnetic recording medium in a predetermined direction, wherein the magnetic recording medium includes a first magnetic layer, and a second magnetic layer as the magnetic recording unit, the magnetic field impression unit directs a magnetization of the first magnetic layer by impressing the magnetic field to the first magnetic layer, and the current supplying unit directs a magnetization of the second magnetic layer in a direction corresponding to a direction of the magnetization of the first magnetic layer by supplying a spin-polarized current to the second magnetic layer through the first magnetic layer.
