    • An optical recording medium is prepared by the use of spiropyrane whose molecular structure contains an alkyl chain having at least 10 more carbon atoms, and by the use of an LB film method or a spin coating method. This recording medium is of a structure wherein when irradiated with the UV, the spiropyrane is photo-isomerized to photomerocyane and, thereafter, when subsequently heated at 35.degree. to 40.degree. C. for 15 minutes, a J-aggregate of the photomerocyane is formed in very stabilized form. When the recording medium is irradiated with light of wavelength of visible spectrum, the color is bleached with the information consequently recorded. The optical recording medium herein disclosed is rewritable and can retain the recorded information for 5,000 hours or more.
    • 通过使用其分子结构包含具有至少10个碳原子的烷基链的螺吡喃以及通过使用LB膜法或旋涂法制备光记录介质。 该记录介质是这样一种结构,其中当用紫外线照射时,螺吡喃被光异构化成光催化剂,然后在35℃至40℃下加热15分钟后,形成光聚合物的J-聚集体 非常稳定的形式。 当用可见光谱的波长的光照射记录介质时,颜色被漂白,随后记录信息。 本文公开的光记录介质是可重写的,并且可以将记录的信息保留5,000小时以上。
