digital versatile disc

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。

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。
