Abstract
A timing recovery scheme with fast acquisition is proposed for a class IV partial response (PR-IV) magnetic recording system. The time infor mation is obtained directly from the coefficients of the channel estim ator. For initial adjustment of the time phase, a known preamble is se nt ahead of the user data and a modified threshold decision is employe d to avoid the hangup effect.
