Abstract
A Data Storage Device (DSD) includes a disk for storing user data in tracks including sectors. Adjacent Track Interference (ATI) values are determined for annular locations along a guard band location designated to not store user data and to separate a first region of tracks from a second region of tracks. Based on the ATI values determined for the annular locations, guard band sectors are assigned from one or more adjacent tracks of the second region corresponding to one or more locations where the one or more adjacent tracks are deemed more susceptible to data corruption based on the determined ATI values. The assigned guard band sectors form part of the guard band. According to one aspect, the ATI values are determined based on at least one Magnetic Recording Metric (MRM) and a track pitch.
