日立制作所中央研究所开发了一种可作为下一代磁盘的相变化型磁盘用的记录材料。该材料是在铟和硒的化合物中混入微量的铊和钴制成的,通过激光加热使之发生相变化,利用膜的结晶状态和非结晶状态的折射率不同而进行记录。这种光盘能长期保
The Hitachi Institute of Central Research has developed a recording material that can be used as a phase change disk for next-generation disks. The material is made of indium and selenium compounds mixed with a trace amount of thallium and cobalt, the phase change by laser heating, the use of the crystalline state of the film and the amorphous state of the refractive index was recorded. This CD can be long-term protection
