Abstract
The invention presents techniques for marking data storage media and responding to disturbances in the marking process. In one embodiment, the invention presents a system that uses a laser to emit a beam to ablate physical marks in a data storage medium. The system includes a sensor such as an optical sensor, configured to detect the position of the data storage medium and to generate a position signal as a function of the position of the data storage medium. An optical device, controlled by an actuator, directs the beam from the laser to an ablation site on the data storage medium as a function of the position signal.
