Title: (EN) OPTICAL INFORMATION-RECORDING MEDIUM AND INFORMATION-RECORDING METHOD
(KO) 광정보 기록 매체 및 정보 기록 방법
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. ©KIPO&WIPO 2008
(KO) 기판 상에 파장이 440nm이하인 레이저 빔의 조사에 의해 정보를 기록할 수 있는 기록층을 포함하는 광정보 기록 매체로서, 상기 기록층은 염료 부분에 공역 결합을 형성하는 것 이외의 방법으로 서로 결합된 2개 이상의 독립 염료 부분을 분자내에 갖는 염료를 포함하는 광정보 기록 매체 및 상술의 본 발명에 따른 광정보 기록 매체에 파장이 440nm이하인 레이저 빔을 조사함으로써 정보를 기록하는 것을 포함하는 것을 특징으로 정보 기록 방법을 제공한다.
