A disk drive includes a rotatable disk, a transducer, an actuator, and a
controller. The disk includes a first servo burst pattern in a first
radial spoke of the disk, and a second servo burst pattern in a second
radial spoke of the disk. The first and second servo burst patterns are
radially offset from each other and are associated with a plurality of
data tracks extending through the first and second radial spokes. The
transducer is configured to read the first and second servo burst
patterns on the disk to generate a servo burst signal. The actuator is
configured to position the transducer relative to the disk. The
controller is configured to control positioning of the transducer
relative to the tracks on the disk based on the servo burst signal.
