Abstract: Various embodiments of a method and system for preserving data of a data storage device are disclosed. The method can include determining a number of times data is written to a target track of a storage medium; rewriting data from a track adjacent the target track if the number of times data is written to the target track exceeds a first predetermined threshold; determining a number of times data is rewritten to the adjacent track; copying data from the target track to a first storage location of a media cache if the number of times data is rewritten to the adjacent track exceeds a second predetermined threshold; writing subsequent data designated for the target track to the first storage location of the media cache; and relocating data from the first storage location of the media cache to the target track.

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.

Abstract: A method and system for preserving data of a storage device are disclosed. In one embodiment, the method includes determining a number of times data is written to a first track in a first region of a storage medium, and rewriting data from a second track that is adjacent to the first track in the first region if the number of times data is written to the first track in the first region exceeds a first predetermined threshold. The method further includes determining a number of times data is rewritten to the second track in the first region, and relocating data from the second track in the first region to a second region of the storage medium if the number of times data is rewritten to the second track in the first region exceeds a second predetermined threshold.
