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.

An optical disc drive is has a voice coil motor that carries and moves focal optics to focus a laser beam onto an optical disc The voice coil motor is responsive to input signals which are based on a calibrated temperature. A temperature measurement is made at the voice coil motor for an operating temperature, and a difference is calculated between calibrated and operating temperatures. The temperature differences are used to calculate adjustment in input signals used to drive the voice coil motors.

Optical density is enhanced on print media darkened by exposure to electromagnetic radiation. The print media is divided into at least one track. A defocused spot of electromagnetic radiation is created within the track. The defocused spot of electromagnetic radiation darkens the print media within the track.

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 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.
