日本NTT公司茨木实验室利用有机着色剂已经研制出一种新型多层光学记录介质。所研制的这种光记录介质由彩色形成体和显象剂构成。当它们混合时就变成彩色。这种彩色形成体和显象剂在塑料衬底上交替形成薄层,着色剂吸收其间的激光束。在原型样 Japan’s NTT company Ibaraki laboratory has developed a new type of multilayer optical recording media using organic colorants. The optical recording medium thus developed consists of a color former and a developer. When they mix, they become colored. The color former and the developer alternately form a thin layer on a plastic substrate, and the colorant absorbs the laser beam therebetween. In the prototype
