1. A data storage device comprising:
- a disk;
a head; and
control circuitry configured to;
first write a plurality of data tracks on the disk;
first generate a metric representing a spacing between at least two of the first written data tracks; and
first rewrite at least two of the plurality of data tracks based on the first generated metric such that the first rewritten data tracks comprise a more equal spacing compared to the first written data tracks.

Abstract
A data storage device is disclosed comprising a head actuated over a disk. A plurality of data tracks on the disk are first written, and a metric representing a spacing between at least two of the first written data tracks is generated. At least two of the plurality of data tracks are rewritten based on the generated metric such that the rewritten data tracks comprise a more equal spacing compared to the first written data tracks.
