日本电信电话研究所利用全息原理开发了下一代超高密度光存储器.其方法是在平滑的信息记录层上设置0.1～0.2μm微小凹凸.若将光横向照射在这个记录层上,则由记录层凹凸入射的光会产生散射.散射光相互干涉便从整个记录层表面垂直产生不同亮度的光,用光敏元件捕捉散射光,经计算机进行处理就可再生信息.试制长2.56mm,宽 The Nippon Telegraph and Telephone Institute developed the next generation of ultra-high-density optical memory using a holographic principle by placing minute irregularities of 0.1 to 0.2 μm on a smooth information recording layer. When light is irradiated laterally on this recording layer, The light incident on the layer will have scattering light scattering light interfere with each other from the entire surface of the recording layer perpendicular to produce light of different brightness with light-sensitive element to capture the scattered light, processed by the computer to reproduce the information trial length 2.56mm, width
