digital versatile disc

Progress of the organic materials used for the new generation high density recordable digital versatile disc

用于新一代高密度可录光盘的有机材料研究进展

These results indicate that the film has a good reflective and absorption characters at the wavelength of 650 nm and is promising for application as recording media for digital versatile disc ( DVD-R).

结果表明在波长650nm处薄膜的折射率为2.19，吸收常数为0.023，具有良好的吸收和反射特性，显示出作为高密度数字多用光盘（DVD-R）记录介质的良好应用前景。

But high def takes up more memory, so a new kind of dvd, digital video or versatile disc, was needed.

但是高清要占用更多的记忆空间，因此需要新型的影碟，比如数字视频光碟或者数字多功能光碟。
