ABSTRACT:
The present invention provides a DSV normal controller and a DSV special controller. In only a predetermined region designated on an optical disc, the DSV special control is performed. The DSV special control causes the absolute value of the DSV to increase so that data will be prevented from being normally reproduced. The normal control causes the absolute value of the DSV to converge at 0. When data is reproduced from the optical disc, if the reproduction state of the predetermined region is abnormal, it is determined that the disc is an original disc. An encryption key can be recorded in the predetermined region.
