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： For at least some layers of a number of stacked layers of an optical disc that correspond to different colors, an optical beam is selectively impinged on a region of the optical disc. The optical beam has a wavelength to which the layer is uniquely sensitive as compared to other of the layers, to sufficiently heat the layer so as to cause the region to change from at least substantially translucent to a color to which the layer corresponds.

摘要： A system for attaching an adhesive backed write-protect ring to an optical disk with the center of the ring aligned to the center of the central hole in the disk. A write-protect assembly is formed from a multilayer material having an adhesive backed label layer and a backing layer. The write-protect assembly includes a removable innermost area that, when removed, forms a hole having a diameter that is the same diameter as the central hole of an optical disk. The innermost area is at least partially surrounded by a ring shaped alignment area that is also removable. Finally, the alignment area is surrounded by the write-protect ring. The central area of the assembly is punched out to form a hole and the backing material is removed from at least part of the write protect area, exposing the adhesive coated surface. The assembly and an optical disk are placed onto an alignment cylinder. The alignment area of the write-protect assembly ensures that the center of the write-protect ring is aligned to the center of the hole in the disk. Finally, the disk with write-protect ring and alignment area attached is removed from the alignment cylinder and the alignment area of the write-protect assembly is removed, leaving just the write-protect ring attached to the disk. The hub of the plastic insert tray of a CD jewel case may be used for an alignment cylinder. In an alternative embodiment of the invention, the write-protect assembly is placed onto the hub first, and the design of the assembly is such that the hub helps remove the central area and the hub helps removal of the backing over the write-protect ring.
