Optical record carrier with a visually detectable pattern as well as an apparatus and a method for recording a visually detectable pattern on an optical record carrier

摘要

A system is described comprising an optical record carrier and an apparatus for recording the optical record carrier. The apparatus comprises a facility (20) for generating a visually detectable pattern at a physical location on the record carrier (40), and a facility (20) for storing pattern information. The pattern information comprises at least first information indicative for the physical location.
