Abstract (en)
[origin: WO2007063458A1] The present invention relates to a method and system of reading/writing data on an optical disc by a plurality of spots positioned along inner tracks to outer tracks of the optical disc. The method comprises the steps of detecting successively that each spot has reached a data area previously read/written; and moving the spot to a position adjacent to the current outermost spot if the reading/writing is done from inner to outer tracks, or to a position adjacent to the current innermost spot if the reading/writing is done from outer to inner tracks.
