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. The time-stamped sync mark detect signal represents a time when the sync mark was detected relative to a servo write clock. A difference between the time-stamped sync mark detect signal and an expected time is computed in firmware to generate a coarse timing recovery measurement used to synchronize the servo write clock. The servo write clock and the head internal to the disk drive are used to write product servo sectors along a substantially circular target path.
