Recording device and recording method

A recording method, comprising:

• focusing light by resonating light within a frequency band of 20 GHz to 1000 GHz with a light focusing unit;
• generating an enhanced magnetic field in which a magnetic field of the light is enhanced;
• applying an external magnetic field from an external magnetic field application unit and the enhanced magnetic field to a magnetic recording medium;
• and
• inverting magnetization of the magnetic recording medium.

A recording device, comprising:

• an external magnetic field application unit that is configured to apply an external magnetic field to a magnetic recording medium;
