<P>PROBLEM TO BE SOLVED: To provide a method for incorporating identification error information in a disk, which is different from the conventional one. <P>SOLUTION: The method for incorporating the identification error information in a disk (6)carrying data manufactured directly or indirectly from a master produced by a manufacturing process controlled by a processing means (34) is provided. The method has a step for supplying identification error data to the processing means and a step for incorporating the identification error data in data to be described in the master when forming the master and providing a disc produced from the master with the identification error information. The identification error data represents an error that occurs during the physical manufacturing process of a disk carrying data and is read by a normal reading process and can be identified. <P>COPYRIGHT: (C)2007,JPO&INPIT |
