    摘要： Various apparatuses and methods for laser positioning in an optical disc drive are provided. In one embodiment, a laser positioning apparatus is provided in which a first positioning assembly positions a first laser beam generated by a first laser and directed toward a first side of an optical disc site in the optical disc drive. A second positioning assembly positions a second laser beam generated by a second laser and directed toward a second side of the optical disc site in the optical disc drive. The second positioning assembly positions the second laser beam independent of the positioning of first laser beam by the first positioning assembly, the second positioning assembly further comprising an actuator that positions the second laser beam, and an elastic member that opposes a movement of the actuator.

    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： A write-protect ring for protecting an optical disk from being written upon is disclosed. The write-protect ring includes an adhesive portion and a non-adhesive portion so that the non-adhesive portion is nearer data regions of the optical disk, thereby preventing the adhesive from interfering with the data on the optical disk. The write-protect ring may also include permanent adhesive which prevents the write-protect ring from being removed from the optical disk without damage to the optical disk.
