摘要
论述了研制磁光盘机械特性测试系统时根据相同位移长度内的光栅信号和光道信号周期数以及光栅信号每mm周期数测量道间距的方法、原理及实现 ,提出了相对基线过零求周期数的方法 ,给出了测量结果 .
The method of the magnetic optical disk pitch test is briefly stated, in accordance with track signal and grating signal cycles in equal length and grating signal cycles in every mm. The principle of the testing method and our implement is introduced. A method of count cycle to use relative base line is expounded. Our measure result is given.
