ROBUST POSITION DETECTION FOR INCREMENTAL RECORDING

摘要

Method for accurately determining the link position for appending new recordings on an optical disc, where address information extracted from the HF data of a previous recording is used in conjunction with position information derived from the pre-groove to determine the link position for the new recording. The pre-groove position information may be derived from the phase of the pre-groove wobble, and the HF data address may be flywheeled to provide a more robust system. The drive may store and update a record table with the begin and end addresses of contiguous previously recorded area, the stored information being used in conjunction with position information derived from the pre-groove to determine the link position for the new recording.
