Abstract
Various systems, methods, and programs embodied on a computer-readable medium are provided for calibrating a laser power in an optical disc drive. In one embodiment, a plurality of marked segments of a calibration pattern are created on a label surface of an optical disc with a laser in the optical disc drive. The marked segments are created by the application of assorted quanta of radiant energy from the laser. The reflectivity of the marked segments is measured. Ultimately, the laser power of a laser in the optical disc drive is set for writing a label based upon the reflectivities measured for each of the marked segments for each quantum of radiant energy.
