DVD盘片反射率和偏心参数的研究

Research on the reflectivity and eccentricity of DVD disc

一、引言近年来,随着光盘领域竞争越来越激烈,质量就是企业的生命,而盘片检测成为质量检测的唯一手段就越发显得重要。

Eccentricity and reflectivity are two important parameters in the optical disc production and detection.According to DVD specifications,these two parameters should satisfy strict requirements.How to properly evaluate the two parameters during DVD detection has become increasingly important.Based on the ASIC ALI5705 disc detection system,this paper discussed these two parameters and the practical detection methods.
