Abstract: Apparatus and method for adaptively mitigating adjacent track interference (ATI) effects on a data recording medium. In some embodiments, a write count value is accumulated for a first track responsive to successive writes to a second track on the data recording medium. For each of the successive writes, the accumulated write count value for the first track is incremented by a different variable amount based on temperature. The first track is refreshed responsive to the accumulated write count reaching a selected threshold value.
