Title:
CIRCUITS, ARCHITECTURES, APPARATUSES, SYSTEMS, ALGORITHMS AND METHODS AND SOFTWARE FOR OPTIMUM POWER CALIBRATION FOR OPTICAL DISC RECORDING
Document Type and Number:
WIPO Patent Application WO/2007/138479
Kind Code:
A3
Abstract:
Methods, software, and apparatus for the calibration of writing characteristics for writing to an optical storage medium, and methods of encoding calibration pattern data and calibration instructions are disclosed. The method of calibration generally includes the steps of (a) receiving pattern data and instructions synchronized with the pattern data, (b) writing the pattern data to the optical storage medium in accordance with the instructions, (c) reading a readback signal corresponding to the pattern data from the optical storage medium, (d) processing the readback signal in accordance with the instructions, and (e) determining a value of a writing characteristic for writing data to the optical storage medium based at least in part on the readback signal. The method provides the ability to flexibly set test parameters and to quickly and accurately test the write characteristics of a recordable or re-writable optical storage medium.
