摘要： PROBLEM TO BE SOLVED: To provide a storage medium using an organic dye material which can be recorded/reproduced by light of a wavelength below 620 nm, and a recording method and recording device using the same. SOLUTION: Light absorption is reduced drastically and recording sensitivity is reduced at the light of a wavelength shorter than 620 nm due to the influence of the absorption spectral characteristics of a general organic dye material. By employing the "L-H" organic dye recording material to make the reflectivity higher than that in a non-recording portion within a recorded portion (recording mark), the need for the substrate deformation is eliminated by the formation of a recording mark using a decoloration effect by separation of electron coupling and recording sensitivity is enhanced.

摘要翻译：要解决的问题：提供使用能够通过波长低于620nm的光记录/再现的有机染料材料的存储介质，以及使用其的记录方法和记录装置。解决方案：由于一般有机染料材料的吸收光谱特性的影响，在波长短于620nm的光下，光吸收显着降低，记录灵敏度降低。通过采用“LH”有机染料记录材料使反射率高于记录部分（记录标记）内的非记录部分的反射率，通过使用脱色法形成记录标记来消除对基板变形的需要通过分离电子耦合和记录灵敏度的效果增强。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a hologram type optical information recording and reproducing apparatus having excellent signal/noise ratio (SN ratio) and suitable for making the capacity of information large and an optical system small-sized. SOLUTION: In the hologram type optical information recording and reproducing apparatus, an optical element having a function for restricting an angle of view is arranged on an optical path of information light beam between a spatial light modulator and the optical information recording medium. The irradiation of the optical information recording medium with reflected light, scattered light and diffracted light from the spatial light modulator is prevented by the optical element to improve the signal/noise ratio.

摘要： PROBLEM TO BE SOLVED: To optimize recording conditions comparatively in a short period of time in an optical disk where multilayer recording is possible.SOLUTION: Information is recorded by using a one side two layers disk (100) of a DRAW type, for example, and forming a mark section and a space section in a data area (DA) using a laser with emission power modulated. When Pp denotes maximum laser power (peak power) when forming the mark section and Pb denotes bias power when forming the space section, a power ratio Pb/Pp is calculated at every recording layer (L0, L1) (ST16) and on the basis of the calculation result, information is recorded on one of two or more recording layers (L0 and/or L1) (ST14 to ST22). By this method, computed power ratio Pb/Pp differs in each recording layer.
