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.

A method for writing data on optical media includes sequentially outputting the same data to an array of laser heads over time so that the laser heads generate laser beams to write the same data to approximately the same location on the media.
摘要:
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.

This disclosure describes a lighting apparatus comprising a light hue modulating device that generates compensating light to adjust the light to a desired hue within a space regardless of the hue of the ambient light within the room.
摘要:
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.
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.
