光磁盘读出信号的傅里叶分析及模拟

Fourier Analysis and Analogue of Magneto-Optic Disc Readout Signal

本文根据光磁盘记录/读出原理,利用傅里叶分析的方法,对读出过程进行了详细分析,导出了读出信号的函数表达式,并对其进行了高精度近似。本文还建立了动态模拟实验系统,为光磁头的优化及均衡网络提供依据。

This paper carefully analyzes the readout process with the method of Fourier analysis according to the principles of recording/readout, and derives the functional expression of readout signal which is approximated high accur ately. The paper also sets up dynamic analogue experiment system. It provides the basis for optimizing magneto-optic head and balancing network,
