  • OPTICAL STORAGE MEDIUM COMPRISING TRACKS WITH DIFFERENT WIDTH AND RESPECTIVE PRODUCTION METHOD
    Publication number: 20100027406
    Abstract: The optical storage medium comprises a substrate layer and a data layer with a mark/space structure arranged in tracks, wherein a sequence of marks of a first track have a first width, and a sequence of marks of a neighboring track have a second width being different from the first width. The optical storage medium is in particular an optical disc, on which the tracks are arranged as spirals, circular rings or segmented circular rings.
