Abstract
A data storage device is disclosed comprising a first disk surface comprising a plurality of data tracks, and a first head actuated over the first disk surface. First data is written to the first disk surface based on a first format. At least part of the first disk surface is reformatted based on a second format, wherein the second format defines a lower recording density for the first disk surface as compared to a recording density defined by the first format. After reformatting the at least part of the first disk surface, second data is written to the first disk surface based on the second format and the first data is read from the first disk surface based on the first format.
