Title (EN) OPTICAL INFORMATION-RECORDING MEDIUM AND INFORMATION-RECORDING METHOD
(FR) MEDIUM D’ENREGISTREMENT OPTIQUE D’INFORMATIONS ET PROCÉDÉ D’ENREGISTREMENT D’INFORMATIONS
Abstract:
(EN) There is provided an optical information-recording medium, comprising a recording layer capable of recording of information by irradiation of a laser beam having a wavelength of 440 nm or less on or above a substrate, the recording layer comprising a dye having two or more independent dye moieties in the molecule that are bound to each other in a manner other than by forming a conjugated bond to the dye moieties, and a method of recording information, comprising recording information by irradiating a laser beam having a wavelength of 440 nm or less on or above the optical information-recording medium according to the present invention described above.
(FR) La présente invention concerne un medium d’enregistrement optique d’informations comprenant une couche d’enregistrement capable d’enregistrer des informations sous l'irradiation d'un faisceau laser de longueur d'onde inférieure ou égale à 440 nm sur ou au-dessus d'un substrat, la couche d'enregistrement comprenant un colorant comportant deux ou plusieurs groupes caractéristiques de colorants indépendants dans la molécule qui sont liés les uns aux autres d’une manière différente qu’en formant un lien conjugué aux groupes caractéristiques de colorant, et un procédé d'enregistrement d’informations comprenant l’enregistrement d’informations par irradiation au moyen d’un faisceau laser de longueur d’onde inférieure ou égale à 440 nm sur ou au-dessus du medium d’enregistrement optique d’information décrit ci-dessus.
