The invention relates to a method and system for recording data by a plurality of laser beams (A, B) on an optical disc, said optical disc comprising segments which (1-51) are each identified by a synchronization pattern, said plurality of laser beams comprising at least a first laser beam (A) which has a first position on said optical disc for recording/reading data on a first segment and a second laser beam (B) which has a second position on said optical disc for recording data on a second segment, said method comprising the steps of: —calculating (410) said second position from said first position and the relative distance between said first laser beam and said second laser beam, —detecting (420) a synchronization pattern by said second laser beam, and —starting (430) to record data with said second laser beam on the basis of said second position and said detected synchronization pattern.
