ＤＶＤ（高密度激光视盘）密度提高，制造条件更加严格，为了保持视盘间的互换性和保证其物理性能，需要对其进行客观的评价。因此，在开发用于ＤＶＤ的视盘和进行质量控制的过程中，非常需要可以检测其物理特性的专用视盘检测仪。视盘检测仪ＤＶＤ一词，现在已经成为报章杂志
DVD (high-density laser disc) density increased, the manufacturing conditions are more stringent, in order to maintain interchangeability between the disc and to ensure its physical performance, it needs to be objectively evaluated. Therefore, there is a great need for a dedicated video disc detector that can detect its physical characteristics during the development of video discs and quality control for DVDs. Disc detector DVD, the word has now become a newspaper magazine
