    摘要: 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 range of reflectivity of an optical disc in the optical disc drive is established. A calibration pattern of marked segments is written to the optical disc and the reflectivity of the marked segments is measured. An average reflectivity is generated for each one of a plurality of laser power settings within the range of reflectivity, thereby obtaining a curve that depicts the average reflectivity with respect to the laser power settings. The laser power setting at a knee of the curve is identified and a slope of the curve at a position on the curve where the average reflectivity decreases as the laser power settings increase is determined. The laser power setting is calculated that results in a predefined darkness based upon the laser power setting at the knee and based upon the slope.

    摘要: 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.

    摘要: Systems and methods for calibrating laser write power in a digital media drive are disclosed. The method includes writing to a calibration portion on a digital media labeling layer with energy from a laser. The writing includes using at least two different laser power settings within the calibration portion. The method also includes measuring a parameter in the calibration segment, the parameter being indicative of the reflectivity of the labeling layer, and determining a calibrated laser write power setting based on the measured parameter and the at least two different laser write power settings.

    摘要: A method is disclosed for positioning an optical labeling mechanism substantially close to a particular track of a labeling surface on an optical disk. The method can include the operation of positioning the optical labeling mechanism adjacent to the particular track. A further operation can be measuring a first surface texture of the labeling surface using the optical labeling mechanism. Another operation can involve positioning the optical labeling mechanism adjacent to a different track. A further operation can be moving the optical labeling mechanism from the different track toward the particular track location. Another operation can involve measuring a second surface texture of the labeling surface using the optical labeling mechanism. A further operation can be comparing the first and second surface textures to determine if the optical labeling mechanism is positioned substantially near the particular track.
