| 术语 | phasechange optical recording |
| 释义 | phasechange optical recording 相变光记录法［技术］ A erasable recording technique. The recording mechanism is based on reversible switching between the amorphous and crystalline status of the materials by heating with a laser. The reading is based on the difference in the optical properties between the two states, e.g., reflectivity. 一门可擦除并重写的记录技术,记录是基于材料的晶体态和非晶体态之间的可逆转换性质,用激光加热 可实现这种转换。读出是基于两个不同状态下有不同的光学性质,如反射率。 |
