Abstract

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.

Description

technical field

[0001] The present invention relates to a host device that can be used in a method for manufacturing an optical recording medium, a device for manufacturing such a host device, a method for manufacturing such a host device, an optical recording medium and a device for manufacturing an optical recording medium. medium method.

[0002] The present invention relates to scanning an optical recording medium with electromagnetic radiation having a wavelength corresponding to visible light. However, it should be pointed out that electromagnetic radiation of significantly shorter or longer wavelengths is also suitable for scanning the recording medium, and that the stated dimensions may vary for these cases. Background technique

[0003] The optical recording medium is manufactured through a multi-stage process using a host device. On the host device, information is stored in a primary track and secondary track structure, and the information is transferred to recor...

Embodiment Construction

[0089] figure 1 Two embodiments of the arrangement of the main track structure 1 and the sub track structure 2 on the host device are shown. exist figure 1 In (a), the main track structure 1 is provided as a substantially uniform surface structure in the track direction. The secondary track structure 2 is likewise provided as a substantially uniform surface structure in the track direction and is arranged on one side of the main track structure 1 , wherein the secondary track structure 2 has breaks. The secondary track structure 2 can also be arranged on the opposite side of the main track structure 1 .

[0090] figure 1 The sub-track structure 2 shown in (b) basically corresponds to figure 1 The sub-track structure 2 in (a), wherein the open circuits in the sub-track structure 2 are larger in the track direction than the substantially uniform surface structure of the sub-track structure 2 in the track direction.

[0091]The main track structure 1 corresponds to the main ...
