摘　　要：针对磁光数据存储系统．研究了差分读出信道的结构不对称性对其噪声性能的影响。研究中发现，差分信道抑制共模噪声的能力取决于信道参数的匹配程度。另外还发现．信道结构不对称将导致信道在读取数据“１”和数据“０”时．信道的噪声强度不同。An analysis is done of the effects of the unsymmetrical structure in differential data channels on noise characteristics for magneto-optical data storage systems. It is found that the capability of differential channels to eliminate common-mode noise is dependent on the match degree of channel parameters. It is also found that the unsymmetrical structure in channels results in the different noise intensities, when the data of '1' and '0' read out.
