Magnetic recording system and magnetic recording device

A magnetic recording device formed with a recording medium, a magnetic field applying part, and an electric applying part, wherein

• the recording medium has a first recording medium layer and a second recording medium layer,
• the first recording medium layer including an antiferromagnetic film configured of an antiferromagnetic material having a magneto electric (ME) effect,
• the second recording medium layer including a ferromagnetic layer configured of a ferromagnetic material and being arranged in a position at which the second recording medium layer exchange-couples to the antiferromagnetic film,
• the magnetic field applying part applies a magnetic field to the recording medium, and
• the electric field applying part has an upper electrode and a lower electrode, and applies an electric field to the recording medium that is arranged between the upper electrode and the lower electrode,
• an applying direction of one of the magnetic field applying part and the electric field applying part is pinned and an applying direction of the other of the magnetic field applying part and the electric field applying part can be reversed by 180°,
• the magnetic field and the electric field to be applied are superimposed to form a superimposition region where both an electric field and a magnetic field are applied, and
• the recording medium is arranged such that the first recording medium layer moves in the superimposition region.
