简要分析了在DVD光盘研究中使用矢量衍射理论的必要性 ,并从光盘信息符横向尺寸、坑深、坡角三个方面综述了利用该理论分析的DVD光盘表面形貌对读出信号的影响 ,从而提出了一些在光盘生产中所需要注意的问题。希望这些论述能对更高密度光盘的研究及工艺的提高起到一些作用。
This paper briefly analyzes the necessity of using vector diffraction theory in the study of DVD disc, and summarizes the influence of the surface morphology of DVD disc on the readout signal from three aspects of the horizontal size, pit depth and slope angle of the information disc of the optical disc , Thus put forward some problems needing attention in the CD production. It is hoped that these discourses will play a role in the research of higher density optical discs and in the improvement of processes.
