In one embodiment, a disk labeling system is configured to use calibration indicia to produce calibration data. A disk is then marked using a laser in a first position. The laser is then deflected from the first position into a second position, by applying an input according to the calibration data. The disk is then marked using the laser in the second position.

Optical disk labeling system and method

A printing method includes providing a device with access to configuration data that can be changed without recompiling printing system software that is used by the device, in conjunction with the configuration data, to perform a printing operation.

Printing method and system

An optical disc has a first plate, a second plate adhered to the first plate, and an optically-activated colorant disposed between the first and second plates.

Optical disc and method of labeling the same

A method for labeling an optically writable label side of an optical disc of one embodiment of the invention is disclosed which includes at least one of the following. First, the method may multiply pass over a track of the optically writable label side of the optical disc with an optical marking mechanism, such that the optical marking mechanism writes to the track during each pass. Second, the method may advance the optical marking mechanism from the track to a next track of the optically writable label side of the optical disc, such that a starting position on the track is radially non-collinear with a starting position on the next track.

A system and method are provided which enable a user of a computer application without administrator privileges to write to a drive without using a third party driver and without using a customized driver acting in conjunction with an IDE bus. The system includes a driver programming interface in communication with the application, a service proxy in communication with the driver interface, a service with administrator privileges in communication with the service proxy, a driver in communication with the service with administrator privileges, and a drive in communication with the driver.

A method for labeling an optically writable label side of an optical disc of an embodiment of the invention rotates the optical disc such that an optical marking mechanism passes adjacent to a track of the optically writable label side of the optical disc a number of times greater than one. During each pass adjacent to the track by the optical marking mechanism, the optical marking mechanism writes a mark at each desired position of a plurality of positions. Each desired position of the plurality of positions has a same number of marks written thereto by the optical marking mechanism equal to the number of times the optical marking mechanism passes adjacent to the track.

Optically marking the label side of an optical disc

A method of an embodiment of the invention rotates an optical disc having an optically writable label side. The optical disc is radially scanned with a laser incident to the optically writable label side, from a first edge of the optical disc to a second edge of the optical disc. While the laser is radially scanned from the first edge to the second edge of the optical disc, a first radius at which markings have not been written to the optically writable label side of the optical disc, next to a second radius at which markings have been written to the optically writable label side of the optical disc, is detected.

An optical pickup unit (OPU) includes a moveable structure that is moved by a voice coil motor component in response to an input signal. The moveable structure includes a pattern that is moved corresponding to the input signal. An encoder reads the pattern to generate an output signal that corresponds to pattern movement as the input signal is applied over a period of time. A controller calculates a calibration factor relating the pattern movement to the input signal.

Multiple passes over tracks of and radially non-collinear track starting positions on label side of optical disc

In one embodiment, a disk shape determining and labeling system includes a first module configured to determine a shape of a non-round disk. A second module determines an orientation of the non-round disk. The labeling system then applies a visible pattern to the disk, wherein the labeling is performed according to the shape and the orientation of the non-round disk.
