Abstract
In one embodiment, a disk labeling system is configured to use calibration indicia to produce calibration data. A disk is then marked using a laser in a first position. The laser is then deflected from the first position into a second position, by applying an input according to the calibration data. The disk is then marked using the laser in the second position.
