Summary:PROBLEM TO BE SOLVED: To provide a system, a method and an apparatus for shingled magnetic recording in a disk drive device.SOLUTION: A method of targeted corruption of user data in a shingled magnetic recording disk comprises the steps of: identifying user data on a Track_N targeted for corruption; identifying a readback centerline of the Track_N; identifying a readback centerline of an adjacent track to Track_N; acquiring user data of the adjacent track; and rewriting the user data of the adjacent track with an offset write centerline to overwrite magnetic material at the readback centerlines of both Track_N and the adjacent track.
