An optical storage disc label recorder includes a first memory portion adapted for storing a first set of track-marking data, the first set of track-marking data defining one or more pre-defined images, each pre-defined image having one or more pre-defined fields for dynamic text content, a second memory portion for storing a second set of track-marking data including the dynamic text content, and a digital processor adapted for combining the first and second sets of track-marking data.

Methods and apparatus for merging pre-rendered and dynamic optical-storage label indicia

A method for labeling a plurality of tracks on a medium is disclosed. The method detects one or more contiguous blank pixels at the conclusion of a data set representing a first track. An ending position for the first track is set at a last non-blank pixel. At least a portion of the first track up to the ending position is labeled before advancing to a second track.

Methods for generating a curved raster image are disclosed. The method includes providing a rectangular raster image, defining a curved raster geometry and coordinate system on a curved track, thus forming a curved raster, and tracing along the curved raster to define a plurality of data locations. The method further includes computing curved raster data for each of the plurality of data locations from the rectangular raster image, thus creating the curved raster image.

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

Imaging layers, imaging media, and methods of preparation of each, are disclosed.

Imaging layers and structures including imaging layers

Media identification control features are read on media. Settings are applied to a label writer based on the media identification control features. A label is generated on the media based on the settings.

Media labeling system

A display device for displaying an image using a first sub-frame and a second sub-frame is provided. The display device comprises an array having a first plurality of pixels and a second plurality of pixels offset from but overlapping the first plurality of pixels and a control unit. The control unit is configured to cause the array to display the first sub-frame using the first plurality of pixels, and the control unit is configured to cause the array to display the second sub-frame using the second plurality of pixels.

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.

In various embodiments, an optical disc drive, programs embodiment in computer readable media, and related methods for writing a label to an optical disc using an optical disc drive. In one embodiment, a label is written on the optical disc, the label being embodied in a plurality of tracks that are written onto a surface of the optical disc. A delay is imposed between the writing of consecutive ones of the tracks in the optical disc drive. The length of the delay is determined in part by a length of time it takes to transition from a completion of a first one of the tracks to a starting position to write a next consecutive one of the tracks.

A method for error detection and correction comprising performing a first modulation error scan of said modulation symbol, marking data that fails to comply with a predetermined criteria, demodulating said modulation symbols, computing a first error syndrome using said demodulated symbols, and correcting errors using said error syndrome computation.

Error detection and correction employing modulation symbols satisfying predetermined criteria

A method of one embodiment of the invention is disclosed that generates a non-Cartesian coordinate system for an optical disc. One or more uniform distances, as well as a plurality of positions on the optical disc, are selected. Each position is separated from adjacent positions by one of the uniform distances, and has a location on the optical disc specifiable to a same degree of precision by at least one integral coordinate.

An integrated system for individually labeling a recording medium at the time that digital information is recorded thereon, by recording write data with a digital recorder on the read/write surface of the CD/DVD and recording image data by inducing visible color change with a laser in laser sensitive materials on the opposite surface of the CD/DVD.

Integrated CD/DVD recording and labeling

A method of one embodiment of the invention is disclosed that is for a track of an optically writable label region of an optical disc having a non-integer number of pixel positions around the track, such that a last fractional pixel position is defined. The method determines whether the size of the last fractional pixel position is greater than a fractional threshold. In response to determining that the size of the last fractional pixel position is greater than the fractional threshold, the method writes a complete pixel to the last fractional pixel position, such that the complete pixel written overlaps onto a first complete pixel position of the track.

Writing pixels to last fractional pixel positions of tracks of optical discs

A method of one embodiment of the invention is disclosed that receives information to be optically written on an optically writable label side of an optical disc. The method formats the information so that the information is optically written on a least number of tracks of the optically writable label side of the optical disc, to minimize optical writing time of the information to the optically writable label side of the optical disc.
