Abstract
A recording media for recording/reproducing information by using an near-field, overcoming a diffraction limit, and having an ultra-high recording density, and a fabrication method thereof, and a recording/reproducing device are disclosed. The optical recording medium includes a planar aperture array which can generate the near-field light, an information recording layer, and a spacer maintaining a predetermined gap between the planar aperture array and the recording layer, the gap being sealed from an external environment. The optical recording/reproducing device is controlled by a macro-servo and a micro-servo, thereby recording/reproducing the information by using the planar aperture array thereof. As a result, the present invention overcomes a diffraction limit, achieves the ultra-high recording density, and thus records a large amount of information even on the small area.
