Abstract
Described are systems and methods during writing of data in hard disk drives in which adjacent track squeeze events are predicted by looking at the difference in position error signal (PES) between two tracks, one PES being a recorded value for data already written, and the other being a predicted value for an upcoming write. This approach recognizes that only using the PES of the track currently being written may not be a reliable indicator of sector failure, particularly in environments susceptible to vibration. This can reducing the unrecoverable error rate while maintaining in-system performance by stopping high-risk writes before they occur and by preventing unnecessary write fault flags.
