A disk drive is disclosed servo written from spiral tracks by generating a time-stamped sync mark detect signal processed by timing recovery firmware. A plurality of spiral tracks are written to the disk, wherein each spiral track comprises a high frequency signal interrupted at a predetermined interval by a sync mark. The head internal to the disk drive is used to read the spiral tracks, and a time-stamped sync mark detect signal is generated when one of the sync marks is detected.
