摘要: 基于光盘的结构,将光盘抽象为一个反射光栅的模型,从而测出了光盘的道间距及信道轨迹长度.

关键词: 光盘, 道间距, 信道, 反射光栅

Abstract: From structure of optical disk, its signal trace can be viewed as a reflection grating, so track pitch of optical disk and the length of the signal trace on a CD can be measured.

Key words: optical disk, track pitch, signal trace, reflection grating
