摘　　要：伺服信号时钟恢复的设计对微硬盘读写通道的性能起着重要的作用,该文提出了一种基于τ因子内插时钟恢复模型用以解决基于锁相环技术的伺服信号时钟恢复存在的不足,并推导出τ因子插值滤波器系数算法。同时对比线性插值算法并给出试验测试结果,从测试结果看基于τ因子内插时钟恢复模型的谐波含量要下降一半。the design of servo signal timing recovery model plays a important role in the performance of read/write channel of micro hard disk. A servo interpolated timing recovery model is proposed based on the T factor, which is used to solve the disadvantages of timing recovery model based on the phase-locked loops. It derives that the arithmetic for r factor interpolator obtains the test result, compared with the a- rithmetic for linear interpolation method which shows that the reduction of content of harmonic is doubled, based on the x factor servo interpolated timing recovery model.
