Abstract:
A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of spiral seed tracks. The head is positioned at a first radial location over the disk, and the head is servoed over the disk in response to the spiral seed tracks starting from the first radial location in order to write a first spiral servo track on the disk. The head is positioned at a second radial location over the disk different from the first radial location, and the head is servoed over the disk in response to the spiral seed tracks starting from the second radial location in order to write a second spiral servo track on the disk.
