Subcode and sector synchronization for a data processing system

摘要

Data synchronization between a data processing system (3) and a servo-system (1) for an apparatus for reading from and/or writing to optical recording media. A method is provided for synchronizing the subcode time codes and sector addresses of data contained on a recording medium. The method comprises the steps of: sending (4) a number of sectors from the micro controller (1) to the data processing system (3); requesting (8) information about the sector headers of the received sectors from the data processing system (3); and calculating (9) the difference between the subcode time codes and the sector addresses using the information about the sector headers.
