可录光盘光学信号和电信号的联系

Relationship between physical parameters and electrical parameters for recordable disc

1前言在竞争日益激烈的光盘复制领域,质量就是企业的生命,而盘片检测是监控质量的唯一手段。光盘检测分为光学信号检测和电信号检测。光学信号检测仪能够实时、快速的发现质量问题, 找到工艺缺陷,在废品大量出现前调整工艺。

Measurement is the only way to monitor and control disc quality.Process stability and replication quality is evaluated by physical test and read(ana/or write) capacity evaluating is done by electrical test. To build the relationship between them is the key to seek the answer of quality control.
