Claim 19:
20. A data storage device, comprising:
a storage medium configured for a plurality of data tracks written in at least one continuous spiral pattern;
a head actuated over a surface of the storage medium; and
a control circuitry configured to write, to the storage medium, data tracks having track lengths that are different than a single revolution of the storage medium, wherein:
the track lengths are comprised of data sectors along the at least one continuous spiral pattern;
the data sectors include sync word fields comprised of sync word patterns;
the data sectors on a first revolution of the at least one continuous spiral pattern have a first sync word pattern;
the data sectors on a second revolution of the at least one continuous spiral pattern have a second sync word pattern;
the data sectors on the first revolution are adjacent the data sectors in the second revolution in a cross-track direction; and
the first sync word pattern is orthogonal to the second sync word pattern.
