Abstract:
A record carrier is described comprising a zone with a visually detectable pattern composed of pattern elements arranged along at least one track. The pattern elements comprise a marked zone having an optical property deviating from a background, the marked zones having a width Wm transverse to the track direction and a length Lm along the track direction, wherein at least two or more pattern elements have a marked zone with a mutually different width Wm.In this way, an increased visibility of the visual pattern is achieved. Likewise a method and an apparatus for recording an optical record carrier is included.
