Abstract: A visible light characteristic changing layer is formed in a location which can be viewed from a part of a label surface of an optical medium. The optical medium is set on a turntable of an optical disk unit, which may be rotated at a constant angular velocity, while the power of a laser beam is modulated in accordance with image data. The optical pickup operates at a first power level when changing a visible light characteristic of the optical medium to form the visible information and the optical pickup operates at a lower power level when not changing a visible light characteristic of the optical medium. As a result, a visible-light reflectivity of the visible light characteristic changing layer is changed, thereby forming a image corresponding to the image data on the label surface. A tracking servo operation is turned off while the optical pickup forms the visible information.

Abstract: An apparatus, system and method of print registration are provided. The invention includes first and second optical channel modules configured to communicate light from a page to a sensor module. The sensor module sums the light from the first and second optical channel modules and detects one or more light transitions as a first registration mark of a first image of the page moves past the first optical sensor module and as a second registration mark of a second image of the page moves past the second optical channel module. The invention determines that the first image and the second image are registered if the sensor module detects a single light transition as the first registration mark and the second registration mark pass the first and the second optical channel modules.

Abstract: An optical scanner emits a light beam in accordance with an image forming signal and deflects the light beam in a first direction. A scanned face is adapted to be scanned by the deflected light beam to form a scanning line while being moved in a second direction perpendicular to the first direction, thereby forming a latent image thereon. A virtual scanned face is defined as a plane including the scanning line and orthogonal to an optical axis of the optical scanner. The shape of a beam spot formed by the light beam incident on the virtual scanned face is approximated to an ellipse. The scanned face is inclined from the virtual scanned face so as to rotate about the scanning line, in accordance with an inclined angle of an major axis of the ellipse from the second direction on the virtual scanned face.

Thereby, high-quality label images can be recorded on the label recording face of the optical disk.

Abstract: In a printing system, a method is used for adjusting currents to LEDs in an LED printbar to achieve uniformity of the print. The line test pattern and halftone strips test pattern are printed. The test patterns are scanned. An LED line metric of each LED test pattern line and reflectance uniformity of each halftone test strip are measured. A line uniformity difference profile and a set of halftone strips uniformity difference profiles are concurrently calculated. A current value supplied to each LED associated with the test patterns is adjusted to simultaneously optimize the uniformity in the lines test pattern and the halftone strips test pattern.
