Abstract
The information recording medium accosting to the preferred embodiment of the present invention achieves high-speed, high-density recording. The layer, in which ultra-particles made from an optical absorption metal, dielectric, or recording material are formed into regular arrays, is deposited. Resonant Plasmon excitation and resonance absorption of ultra-particles enable the edges of the recorded marks to be identified clearly and intense absorption to occur only in the given layer depending on the wavelength in the case of the multi-layer medium achieving high-density, large-capacity recording.
