Abstract:
Disc drive data recovery methods and systems that utilize off center track information are provided. A disc drive data track is illustratively read at a first position along a width of the data track and at a second position along the width of the data track. The data read from the track is stored and tagged with indications of the first and the second positions. The tagged data is optionally used to calculate average waveforms for each of the first and the second positions and to identify the average waveform having the highest signal-to-noise ratio.
