Abstract
In a data storage device, a head writes data so as to protect data from off track writing to adjust tracks. A control unit acquires large ring buffer during sequential writing and performs a retry to return adjacent tracks, according to data of a return sector area of the ring buffer when a write error occurs. A write error due to a detection mistake of an off track error can be prevented.
