摘要：
A reproducing method for a record medium includes the steps of performing a demodulating process for data that have been read from a record medium on which content data have been recorded, management information and additional information being embedded in the content data, the management information being with respect to a copy management, the additional information containing one of error detection code and error correction code added to the management information, detecting the additional information from a demodulated output signal, performing an error detecting process corresponding to one of the error detection code and the error correction code, and controlling an output operation for the demodulated output signal for the content data read from the record medium corresponding to the management information when no error is found in the error detecting process.
