基于光盘的读写原理,提出了采用弹性支承振动台代替光盘系统中精密回转台,以实现在没有自动调焦和轨迹跟踪伺服系统情况下对光盘记录介质进行动态检测的简单方法。以TeSeIn相变光盘记录介质为例进行了检测,结果表明这种方法是简单可行的。 Based on the principle of read and write of optical disk, a simple method of using dynamic supporting vibrating table instead of precision turntable in optical disk system is proposed to realize the dynamic detection of optical disk recording medium without automatic focusing and tracking servo system. TeSeIn phase change optical disc recording media as an example was tested, the results show that this method is simple and feasible.
