    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: 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: An optical system for writing on a double-sided medium is disclosed. A beam source is configured to generate a light beam in a first direction relative to a first side of the medium. A steering mechanism is able to direct the light beam in a second direction substantially along the first side, such that the light beam is configured to impinge on a first reflector. The first reflector is able to reflect the light beam in a third direction, such that the light beam is routed outside a substantially opaque annulus of the medium, and is configured to impinge on a second reflector. The second reflector is able to reflect the light beam in a fourth direction substantially opposite the second direction, such that the light beam is configured to impinge on a third reflector. The third reflector is able to reflect the light beam in a fifth direction substantially toward a second side of the medium opposite the first side, such that the light beam strikes the second side of the medium.
