摘要： A unique recording medium having identification information such as a serial number or ID number inherent in the recording media as information signals recorded thereon, which is prevented from being easily erased or rewritten, without inducing the complexity of an optical disc reproducing apparatus in its configuration and the intricacy of the reading-out operation is realized. Recognition information is recorded to a recording medium which has a recognition information recording area for recording the recognition information, and at least the recognition information recording area is capable of additionally having information recorded thereto. In recording digitized recognition information to the recognition information recording area, the “1” is modulated to a signal having a first frequency and the “0” is modulated to a signal having a second frequency, and the signals corresponding to their respective frequencies are written to the recognition information recording area.
