For each of a number of regions of a label surface of a substrate that are to be optically written to form a human-readable image, a corresponding power level at which an optical beam is to impinge the region to optically write a desired mark to the region as part of the image is determined. The optical beam impinges the region by being switched on and off from a higher power level to a lower power level to achieve the corresponding power level on average. At least one of the following are adjusted: a number of times the optical beam is switched on and off, a length of time the optical beam remains on each time it is switched on, and a duty cycle of the optical beam while the optical beam is positioned over the region.

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.

A thermally sensitive medium includes at least one layer of temperature-activated dye, and antenna molecules disposed in the layer of temperature-activated dye for converting radiant energy into thermal energy. A system for forming an image on a thermally sensitive medium includes a radiant energy source for selectively heating portions of the thermally sensitive medium to activate temperature-activated dyes of the medium. A method of forming an image on a thermally sensitive medium having multiple layers of temperature-activated dyes is performed by selectively heating portions of each of the layers of temperature-activated dyes with a light source to form the image.

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.

摘要:
A method of one embodiment of the invention is disclosed that outputs an oscillating wave towards a surface of an optical disc. A proximity signal is detected in response to the oscillating wave being output towards the output of the optical disc, and denotes closeness of the oscillating wave to the surface. A number of peaks within the proximity signal are determined. Each peak corresponds to the oscillating wave crossing the surface of the optical disc. The time at which each peak within the proximity signal occurs is correlated with a value of the oscillating wave at that time, yielding a number of time-value pairs. The topology of the surface of the optical disc is approximated from these time-value pairs.
