Zusammenfassung:A sync mark correction for holographic data pages is provided to detect data in the zone of sync mark of which position is missed or wrong using the presumed sync mark position. A sync mark correction for holographic data pages comprises a step of distinguishing the sync mark(2) of which position is missed or wrong in read data pate(1); a step of estimating the corrected sync mark position; and a step of using corrected sync mark position. The addition al data process comprises a step of detecting data in the zone of sync mark using the estimated sync mark position.
