Patent ID: 8094487

Claim:
A method for read-out of information in a magnetic recording element, the method comprising: preparing a magnetic recording element including a magnetic free layer where a magnetic vortex is formed; assigning “0” or “1” according to a core orientation of a magnetic vortex formed in the magnetic free layer; rotating the magnetic vortex core formed in the magnetic free layer on the magnetic free layer by applying a current or magnetic field, of which a direction varies with time, to the magnetic free layer with the magnetic vortex formed; and reading “0” or “1” assigned according to the core orientation of the magnetic vortex formed in the magnetic free layer by measuring a characteristic caused by a difference in a rotation radius of the magnetic vortex core, wherein the rotation radius of the magnetic vortex core that rotates by the applied current or magnetic field varies with the core orientation of the magnetic vortex formed in the magnetic free layer.
