摘要
采用脉冲响应函数方法,分析光盘存储系统中光学头存在各种象差及伺服误差时,对读出信号信噪比的影响,从而导出了各类光学头的象差容限及伺服要求。
By using the impulse response function, the effects of aberration of optical head and the servo-error of the optical storage system on SNR of the read-out signal are discussed. The aberration tolerance and the servo-requirement for various optical head are presented.
