Abstract
Determining a beam size of an emitter for a data storage medium is disclosed. The emitter, having an emitted beam, is moved across conductor of a detector. Current through the conductor, resulting from the emitted beam as the emitter moves across the detector, is measured. The size of the emitted beam of the emitter is determined based on the position of the emitter and the measured current.
