One embodiment of an optical medium includes a substrate, a data recording layer positioned on the substrate, a selectively transmissive layer positioned on the data recording layer, and a label recording layer positioned on the selectively transmissive layer, the label recording layer optically accessible at only certain wavelengths through the data recording layer and through the selectively transmissive layer.

Substrates, coatings and methods for marking substrates using the coatings. The substrate contains a coating of encapsulated marking materials. Capsules of the encapsulated marking materials are designed to preferentially absorb a predetermined wavelength of light or range of wavelengths of light. The capsules contain color chemistry capable of activation by the predetermined wavelength of light or range of wavelengths of light for the generation of a color response. By utilizing capsules of differing color chemistries, such substrates are capable of multi-color image generation.

Whether an optically writable label surface of an optical disc is suitable for having an image formed thereon is determined. A detectable number of encoder spokes on a control feature area of the optical disc is counted as the optical disc is rotated. Where the detectable number of encoder spokes is other than a predetermined value, an error condition with respect to the optically writable label surface of the optical disc is indicated.

In one embodiment, a printing device includes: a print engine configured to apply marking material to print media; a laser writer configured to expose the print media to a laser beam of sufficient energy to change the reflectivity of exposed portions of the print media; a media path along which the print engine may apply marking material to print media in a macro printing zone and along which the print media may be exposed to a beam of light emitted by the laser writer in a micro printing zone; and an electronic controller operatively connected to the print engine for selectively applying marking material to the print media and to the laser writer for selectively exposing the print media to a laser beam.

An optical disc device includes a first optomechanical mechanism, a second optomechanical mechanism, and a positioning mechanism. The first optomechanical mechanism is located under an optical disc insertable into the optical disc drive to optically access a bottom surface of the optical disc. The second optomechanical mechanism is located over the optical disc insertable into the optical disc drive to optically access a top surface of the optical disc. The positioning mechanism is to precisely locate the second optomechanical mechanism over the optical disc for optically accessing the top surface of the optical disc and to prevent the second optomechanical mechanism from interfering with movement of the optical disc during insertion and removal of the optical disc into and from the optical disc drive.

A medium includes a plurality of Fabry-Perot cavities of varying depths. The cavities correspond to different colors which are produced by the respective cavities under incident light. A thermo-sensitive material covers the plurality of cavities. The cavities are selectively exposed by heating portions of said thermo-sensitive material to alter the thermo-sensitive material where heated thereby forming an image.

Opto-mechanical adjustment based on sensing the label side of an optical disc is disclosed. The label side of the optical disc is first sensed with an opto-mechanical system. The opto-mechanical system is then adjusted, based on the label side of the optical disc as sensed, for future writing on the label side of the optical disc.

A method for calibrating an interferometer uses an actuator adapted to control an optical gap in response to application of an electrical signal. The interferometer is illuminated with a beam of light having a predetermined substantially monochromatic wavelength, oriented at a first predetermined angle of incidence, and light reflected from the interferometer at a second predetermined angle is detected while varying an electrical signal applied to the actuator, thereby establishing a calibrated relationship between the applied electrical signal and an optical path length of the interferometer.
