Abstract
Example control circuitry, data storage devices, and methods to provide a spiral data track format that is different from the underlying servo track format are described. The data storage device may include a storage medium configured with a plurality of tracks in at least one continuous spiral pattern and a head actuated over the storage medium. The data tracks may be written to the storage medium with track lengths that are different than a single revolution of the storage medium.
