ABSTRACT:
Multilayer optical disk is recordable or partly recordable. Parallel reading of information data from the group of layers by the same focused laser beam is possible. Only one layer of said group has the guide grooves for tracking. Alignment of the information data disposition on the layers of the group is provided. The signals reflected from the different layers of the group have different tilts and are directed onto the different photodetectors. Optical disk management for preventing its illegal use is proposed.
