Abstract
The disclosed technology provides for a method and system comprising determining a write-encroachment threshold of a recording medium, determining a track as off-track and one or more tracks substantially near the off-track as unwriteable, flagging the one or more tracks substantially near the off-track 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.
Claims20
A method comprising:
- determining a write-encroachment threshold (WET) of a recording medium;
- determining a track as off-track and one or more tracks substantially near the off-track as unwriteable;
- flagging the one or more tracks substantially near the off-track track;
- and
- writing write data for the one or more flagged tracks to a media cache.

A storage device system, comprising:
- a memory configured to store data on data tracks;
- and
- a processor configured to determine a write-encroachment threshold (WET) of a recording, determine a track as off-track and one or more tracks substantially near the off-track as unwriteable, flag the one or more tracks substantially near the off-track track, and write write data for the one or more flagged tracks to a media cache.

- flagging the one or more tracks substantially near the off-track track;
- writing write data for the one or more flagged tracks to a media cache;
- and
- determining a +WET and a −WET and determining off-track tracks exceeding the +WET and the −WET.
