Abstract
Embodiments described herein provide methods and systems for correcting a transient phase error induced while recording on a magnetic recording medium. An input signal is received and is distributed to a plurality of sinc filters. A respective phase-shifted signal is generated at each of the plurality of sinc filters by adding a corresponding predetermined amount of phase to the received signals. A respective score is assigned to each of the generated phase-shifted signals. The generated phase-shifted signal having the highest score is selected as the phase-corrected signal to compensate for the transient phase error induced while recording on the magnetic recording medium.
