Abstract:
Various systems, methods, and programs embodied on a computer-readable medium are provided for calibrating a laser power in an optical disc drive (100). In one embodiment, a plurality of marked segments (173) of a calibration pattern (166) are created on a label surface of an optical disc (136) with a laser (140) in the optical disc drive (100). The marked segments (173) are created by the application of assorted quanta of radiant energy from the laser (140). The reflectivity of the marked segments (173) is measured. Ultimately, the laser power of a laser (140) in the optical disc drive (100) is set for writing a label based upon the reflectivities measured for each of the marked segments (173) for each quantum of radiant energy.
Abstract:
An optical focusing system (100) is configured to generate a data profile (296), wherein the data profile (296) is configured to provide signals (293) for operation of an actuator (200). Application of the signals (293) from the data profile (296) results in focus of optics (209) within a label region (221) of an optical disc (217). An image (165) is printed on the label region (221) of the optical disc (217) while the optics (209) focus on the label region (221) of the optical disc (217) by applying signals (293) to the actuator (200) according to the data profile (296).

Abstract:
Optical density i.e. an area that appears to a user to have full absorption and appears black is enhanced on print media (6) darkened by exposure to electromagnetic radiation. The print media (6) is divided (24) into at least one track (20). A defocused spot of electromagnetic radiation is created (26) within the track (20). The defocused spot of electromagnetic radiation darkens (28) the print media (6) within the track (20).
