Patent ID: 7000171

Claim:
A reproducing apparatus for a record medium, the reproducing apparatus comprising: a head portion for scanning a record medium on which content data are recorded, wherein management information and additional information are embedded in the content data; the management information correspond to copy management; and the additional information contains one of error detection code and error correction code added to the management information; a demodulation processing portion for performing a demodulating process on data read from the record medium by the head portion; a detecting circuit portion for detecting the additional information from an output signal of the demodulation processing portion; and a determining circuit portion for performing an error detecting process on a detected result from the detecting circuit portion corresponding to the error detection code contained in the additional information detected by the detecting circuit portion and controlling an output operation for the output signal of the demodulation processing portion for the content data read from the record medium corresponding to the management information when no error occurs in the error detecting process.
