摘　　要：针对磁光存储系统中的非平衡差分信道建立了描述其信道特性的信噪比模型，并就其读出特性与平衡差分信道进行了比较。The characteristics of the unbalanced differential channels is modeled for the magneto optical storage system,and the readout characteristics are compared with that of the balanced channels.It is shown that the signal to noise ratio in the unbalanced channels is only a bit lower than that in the balanced channels.
