Systems and methods for adjacent track interference based re-writing

摘要

Systems and method relating generally to data processing, and more particularly to systems and methods for confirming data validity. In one case, a system is disclosed that includes an adjacent track interference confirmation circuit. The adjacent track interference confirmation circuit is operable to receive an indication of an adjacent track interference; determine a causal connection between the adjacent track interference and a mis-alignment of a read head and a track on a storage medium from which a data set corresponding to the indication of the adjacent track interference is derived; and provide a re-write signal where even after reduction of the mis-alignment the indication of adjacent track interference repeats.

an adjacent track interference confirmation circuit operable to:
receive an indication of an adjacent track interference;determine a causal connection between the adjacent track interference and a mis-alignment of a read head and a track on a storage medium from which a data set corresponding to the indication of the adjacent track interference is derived; andprovide a re-write signal where even after reduction of the mis-alignment of the read head and the track, the indication of the adjacent track interference repeats.
