Abstract
The disclosed technology provides for a method and system comprising determining a write-encroachment threshold of a recording medium as a percentage of cross-track width of tracks in the recording medium, determining a track as off-track based on a position error signal level for the track exceeding the write-encroachment threshold, flagging one or more tracks substantially near the off-track, and writing write data for the one or more flagged tracks to a media cache. In a recovery process, the write data can be later transferred back to the flagged tracks.
