Abstract:
An optical recording medium to be used for a retail activation solution is proposed. The optical recording medium is a modified ROM disk that can only be played after the application of an activation process. For this purpose at least a part of a reflective layer of a read-only area of the optical recording medium is replaced by a light sensitive layer stack that changes its reflectivity upon illumination.Also proposed are a method for producing such an optical recording medium as well as methods and apparatuses for initializing and/or activating such an optical recording medium.
