Patent Number Title Of Patent Date Issued
7701479 System and method for laser write power calibration April 20, 2010
Systems and methods for calibrating laser write power in a digital media drive are disclosed. The method includes writing to a calibration portion on a digital media labeling layer with energy from a laser. The writing includes using at least two different laser power settings within the
7639272 Device and method for optical scanning December 29, 2009
An optical scanning device and method are provided for marking an optically sensitive layer. The device can include an optical source capable of emitting a beam. At least one pivot can be configured to enable the beam to travel through a beam output arc. In addition, a mirror surface
7576765 Methods and apparatus for detecting and optimizing laser mark quality on recording media August 18, 2009
A method for detecting and optimizing the quality of a mark made by a laser on a recording medium, comprising (a) recording a test mark at a selected level of laser power and a selected speed of movement of the recording medium, (b) measuring at least one dimension of the test mark,
7515165 Laser power calibration in an optical disc drive April 7, 2009
Various systems, methods, and programs embodied on a computer-readable medium are provided for calibrating a laser power in an optical disc drive. In one embodiment, a plurality of marked segments of a calibration pattern are created on a label surface of an optical disc with a laser in
7420580 Laser power calibration in an optical disc drive September 2, 2008
Various systems, methods, and programs embodied on a computer-readable medium are provided for calibrating a laser power in an optical disc drive. In one embodiment, a range of reflectivity of an optical disc in the optical disc drive is established. A calibration pattern of marked s
7268795 Labeling methods and apparatus using electromagnetic radiation September 11, 2007
A method and apparatus are provided for visually marking a recording medium by inducing a phase change in a light-sensitive surface by heat absorption from laser radiation. The method includes applying the laser radiation to a desired portion of the light-sensitive surface according
7233557 Method for identifying location on an optical disk June 19, 2007
A method is disclosed for positioning an optical labeling mechanism substantially close to a particular track of a labeling surface on an optical disk. The method can include the operation of positioning the optical labeling mechanism adjacent to the particular track. A further opera
6765937 Apparatus and method for analysis and control of timing of a train of high speed, high power las July 20, 2004
An apparatus and method for flexibly and precisely varying temporal placement and duration of pulses, within a train of high speed, high power optical pulses. The invention includes optics adapted for focusing on a layer of an information storage media. An optical pulse generator is
6744712 Optical disc drive with satellite beams for generation of quadrature error signals for radial po June 1, 2004
In an optical disc drive, signals from two satellite spots are used to cancel DC offset from a tracking error signal, and for generating a quadrature signal for determining direction of radial movement. The two satellite spots generate signals that are out of phase with the main trac
