Abstract
A disk drive is disclosed comprising a head actuated over a disk including a plurality of contiguous servo tracks for defining a plurality of data tracks. A first write command comprising first write data is received, and a first density of first data tracks over a first plurality of the contiguous servo tracks is selected, wherein the first write data is written to the first data tracks. A second write command comprising second write data is received, and a second density of second data tracks over the first plurality of the contiguous servo tracks is selected, wherein the second density is different than the first density. The second write data is written to the second data tracks.
