Abstract
The present invention relates to a format of a recordable optical recording medium, which is designed in such a way that it can be read by any standard player and recorder. The optical recording medium has a recording layer with a structure of lands and grooves, which generates a strong push-pull signal in an area of the recording layer without recorded marks and a small push-pull signal in an area of the recording layer with recorded marks.
