摘　　要：分析了在峰值检读方式下磁光存储系统产生误码的原因．并考虑多种定时误差的存在，导出了描述信道误码特性的数学模型．在此基础上分析了磁光信号检偏方式与信道误码特性的关系，分析结果表明平衡差分信道的容错能力略高于非平衡差分信道．An analysis of the Causes which result in bit errors is given for magneto-optical Storage systems with zero-crossing detection. in consideration of Several kinds of Timing errors. a mathematical model of describing the bit error characteristics in the channel is derived. .Also. an analysis of the relationship of the signal detection method and the bit error characteristics is presented. It is shown that the fault fredom in balanced differential channels is better than that in unbalanced differential channels.
