A timing recovery scheme with fast acquisition is proposed for a class IV partial response (PR-IV) magnetic recording system. The timing information is obtained directly from the coefficients of the channel estimator. For initial adjustment of the timing phase, a known preamble is sent ahead of the user data and a modified threshold decision is employed to avoid the hangup effect.
