摘要： PROBLEM TO BE SOLVED: To provide a storage medium using an organic dye material that records or reproduces with light of a wavelength of 620 nm or less, and to provide a recording method and apparatus using the medium. SOLUTION: The absorptance of the light of a wavelength shorter than 620 nm is significantly decreases to decrease recording sensitivity due to the influence of absorption spectroscopic characteristics of a general organic dye material. An "L-H"organic dye recording material whose reflectance is higher in a recorded part (a recording mark) than in a non-recorded part. The recording mark is formed by using discoloring action due to separation of electronic coupling, thereby eliminating the need of forming a substrate, while improving the recording sensitivity.

摘要翻译：要解决的问题：提供使用用620nm或更小波长的光记录或再现的有机染料材料的存储介质，并提供使用该介质的记录方法和装置。解决方案：由于一般有机染料材料的吸收光谱特性的影响，波长小于620nm的光的吸收率显着降低，从而降低记录灵敏度。在记录部分（记录标记）中反射率高于非记录部分的“L-H”有机染料记录材料。记录标记由于分离电子耦合而使用变色作用形成，从而消除了形成基板的需要，同时提高记录灵敏度。版权所有（C）2011，JPO＆INPIT
