Abstract
A disk drive is disclosed comprising a disk surface having a plurality of servo sectors for defining a plurality of servo tracks, and a head actuated radially over the disk surface. A first servo sector defines a first servo track comprising a first track address having a first width, and a second servo sector defines a second servo track comprising a second track address having a second width substantially less than the first width. In one embodiment the servo sectors are written using an external servo writer or media writer, and in another embodiment the servo sectors are self-servo written by the disk drive.
