摘要：
A system and method in which read information is calculated with additional information as a coefficient and has superior in quality to basic information. The read information contains a larger amount of information than the basic information. So, even if an attempt is made to record the read information as it is to any other recording medium, the recording medium having a sufficiently large capacity for storage of the read information. Thus, copy of recorded data in the recording medium to any other recording medium is difficult.
