Title:
A system for the tile writing magnetism record in disk driving, a method, and a device
Document Type and Number:
Japanese Patent JP5904934
Kind Code:
B2
Abstract:
A method of targeted corruption of user data in a shingled magnetic recording disk includes 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.
