An optical recording member comprising a recording layer containing a light absorbing substance supported on a substrate in which recording is made by the thermal deformation of the recording layer owing to laser beams and reproduction is made by the reading the difference of the reflection between the non-deformation portion and the deformation portion, said light absorbing substance being represented by the following formula:
wherein one of X and Y is -O(C₂H₄O)nR wherein R is an alkyl group which may be branched and n is a number of from 1 to 6, and the other is a hydrogen atom, and A is VO, Cu, Ni or Co.
一种光学记录部件,包括支撑在基底上的含有光吸收物质的记录层,其中通过记录层在激光束作用下的热变形进行记录,并通过读取非变形部分和变形部分之间的反射差进行再现,所述光吸收物质由下式表示:
其中 X 和 Y 中的一个是 -O(C₂H₄O)nR,其中 R 是烷基,可以是支链,n 是 1 到 6 的数字,另一个是氢原子,A 是 VO、Cu、Ni 或 Co。
