Abstract
A data storage device is disclosed comprising a head and a disk comprising servo information and a reference pattern comprising a plurality of magnetic transitions. The servo information on the disk is processed to actuate the head over the disk, and a read signal is sampled from the head as the head moves across a width of the reference pattern at a substantially constant velocity to generate signal samples. The signal samples are processed to characterize a geometry of the magnetic transitions.
