Near field optical recording/reproducing device

摘要

High density near field optical recording/reproducing device, including a light source for emitting a beam of light, a converging lens (12) for converging the light emitted from the light source, and a near filed light generating part (13) formed of a material of which light transmittance is varied with light temperature sectors, thereby overcoming a limit of resolution coming from diffraction, whereby increasing a recording density, significantly. <IMAGE>
