摘要
文中建立了便于理论分析的光记录读出信号模型和离散通道模型．对均衡器对记录密度的影响进行了分析，证明了判决反馈均衡器比线性均衡器提高记录密度约５０％．
A theoretical optical recording readout model and a discrete channel model are established. The relationship between equalizers and the recording density is analyzed. It is demonstrated that the adoption of the feedback equalizer instead of the linear equalizer can improve the density about 50%.
