A study of timing recovery for perpendicular magnetic recording

Abstract Performance of a timing recovery system for perpendicular magnetic recording channels is studied. The system detects timing error from pre-equalized waveform of a basic PR system such as PR1, and corrects the timing of sampled sequence using an interpolated filter. The results show that the system which uses PR1 system as the pre-equalization and directly compensates the reproduced waveform exhibits good performance.
