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.

A system and method for synchronization of a pixilated labeling media and a digital medium are disclosed. The digital medium includes a substrate and a pixilated labeling layer disposed on the substrate. The labeling layer includes a plurality of color pixels adapted to form a predetermined color when activated and a plurality of synchronization pixels interspersed among the color pixels. The synchronization pixels are distinguishable by a sensor from the color pixels prior to activation of the color pixels.

An optical disk includes a label region having writable material. Disk speed features are located in a manner which allows them to be readable when writing to the label region.
摘要:
An optical focusing system is configured to generate a data profile, wherein the data profile is configured to provide signals for operation of an actuator. Application of the signals from the data profile results in focus of optics within a label region of an optical disc. An image is printed on the label region of the optical disc while the optics focus on the label region of the optical disc by applying signals to the actuator according to the data profile.
摘要:
A digital video recorder is configured with an interface to receive broadcast content. A user input device allows specifying label data related to the broadcast content. An optical disc drive of the digital video recorder writes the broadcast content to an optical disc and electro-optically labels the optical disc with the specified label data.
