Magnetic recording apparatus and magnetic recording method

A magnetic recording apparatus comprising:

• a magnetic recording medium having a first magnetic layer and a second magnetic layer;
• a magnetic field impression unit that impresses a magnetic field to the first magnetic layer;
• a current supplying unit that supplies a current to the second magnetic layer through the first magnetic layer;
• and
• a controlling unit that makes the current supplying unit supply the current to the second magnetic layer through the first magnetic layer while making the magnetic field impression unit impress the magnetic field to the first magnetic layer to direct a magnetization of the first magnetic layer in a predetermined direction, thereby making a direction of a magnetization of the second magnetic layer in a direction corresponding to the direction of the magnetization of the first magnetic layer.

A magnetic recording method comprising:

• impressing a magnetic field to a first magnetic layer to direct a magnetization of the first magnetic layer;
• supplying a current to a second magnetic layer of the magnetic recording medium through the first magnetic layer;
• and
• making a direction of a magnetization of the second magnetic layer in a direction corresponding to the direction of the magnetization of the first magnetic layer thereby recording an information magnetically.
