| 摘 要： | By using the super-resolution near-field structure （super-RENS） method, the super-resolution recording marks are obtained practically by an organic photochromic diarylethene mask layer, under much lower recording laser power of 0.45roW. The size of recording marks is decreased by 60% （from 1.6μm to 0.7μm） for a diarylethene （photo-mode） recording layer by the optical detection method （limited by optical diffraction）, or decreased by 97% （from 160Onto to 5Onto） for a heptaoxyl copper phthalocyanine （thermo-optical） recording layer, the latter is much smaller than the limitation of optical diffraction. In order to obtain a desirable result, a proper extent of photochemistry reaction in the mask layer is needed. Thus, the super-resolution recording marks can be obtained by adjusting the concentration of diarylethene in the mask layer, the recording laser power, and the moving speed of the sample disc.
