Zusammenfassung:	The proposed method for recording identification marks on a compact disk can be used for protection against unauthorized copying and propagation of compact disks. The method consists in recording, by a laser beam, holographic identification marks on the information tracks of the compact disk. Each mark is designed as a set of dashed lines, which are arranged an angle of 45 ... 90 degrees to the line that is tangential to the information track. The proposed method provides a possibility to increase the brightness of the identification marks without distorting the records on the information tracks.
