    • A process for storing information in an organic recording layer which, when treated locally with an organic solvent in accordance with the input of information, is able to change its absorption spectrum and/or its photoconductivity such that information can be produced or stored at the treated areas of said layer, wherein the organic solvent is solid at room temperature and is present in the recording layer, or by decomposition of a solid organic precursor which is present in the recording layer, and said solvent is vaporized or melts by the action of laser beams in accordance with the input of information, or said precursor is decomposed by the action of laser beams in accordance with the input of information.The stored information can be read out with a photodetector in the visible or near NIR range or with a built-in electrode system.
    • 一种用于将信息存储在有机记录层中的过程,当根据信息的输入在有机溶剂中局部处理时,能够改变其吸收光谱和/或其光电导率,从而可以在处理过的信息中产生或存储信息 所述层的区域,其中有机溶剂在室温下为固体并存在于记录层中,或通过存在于记录层中的固体有机前体的分解,并且所述溶剂通过激光的作用而蒸发或熔化 根据信息的输入,或者所述前体根据信息的输入被激光束的动作分解。 存储的信息可以用可见光或近NIR范围内的光电探测器读出,也可以用内置的电极系统读出。
