ABSTRACT:
The misplacement of a servo burst during a servowriting or self-servowriting process can be corrected by erasing and re-writing that burst. In addition, WORF information of a track can be saved in memory for future servowriting and/or can be utilized to compare with a pre-determined threshold to identify servo bursts to be repaired. Alternatively, a batch writing approach can be used to minimize the time needed to re-write misplaced bursts. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
