Abstract: The present invention provides for method of seeking synchronization at a data interface between a transmitting element and a receiving element, and to related transmitting and receiving elements of the interface, in which the clock frequency of both elements is the same but which exhibit a phase difference, also known as mesochronous clock domains, the method including the steps of, prior to data transfer at the interface, delivering a strobe signal generated at the transmitting element to the receiving element, generating a strobe signal at the receiving element and synchronizing the same to the strobe signal received from the transmitting element, and maintaining the synchronized strobe signal generated at the receiving element for the sampling of data appearing at the interface from the transmitting element.

Abstract: 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.
