ABSTRACT:
A guarantee processing method guarantees the data of an adjacent track in the case of a write fault when there is a possibility of an off track write. Even if a write fault is detected or an offset read retry is successful, a rewrite for guaranteeing an adjacent track is not executed immediately. The possibility of an off track write is judged by the movement of the head, and only the sector which is difficult to read due to the off track write is rewritten.
