Abstract (en)
[origin: WO2008148567A1] The invention relates to a master device which can be used in a method for producing a recording medium. A substantially spiralling or concentrically extending main track structure and at least one substantially spiralling or concentrically extending secondary track structure are configured on the master device. The secondary track structure is arranged at least on one side of the master track structure, and the secondary structure has disruptions varying an optically detectable surface property of the recording medium to such an extent that a first auxiliary information is produced on the recording medium.
