Abstract:
1. A digital information recording and reproducing apparatus for inputting digital information and for recording and reproducing the input digital information, comprising: a detector circuit for detecting copy control information accompanying the input digital information, the copy control information indicative of whether or not the input digital information can be copied; an encrypting circuit for encrypting the input digital information; a first recording circuit for recording to a first recording medium the input digital information encrypted by the encrypting circuit and the copy control information; a reproducing circuit for reproducing the encrypted digital information and the copy control information recorded to the first recording medium and for decrypting the encrypted digital information; a second recording circuit for recording to a second recording medium digital information reproduced by the reproducing circuit; and a control circuit for controlling the first and second recording circuits and the reproducing circuit, wherein when the copy control information that is stored on the first recording medium is detected by the detector circuit as being of type Copy One Generation, which indicates that copying of only one generation of the digital information is allowed so that the digital information is restricted in the number of times it can be transferred, then the control circuit controls the second recording circuit and the reproducing circuit such that the digital information reproduced by the reproducing circuit is recorded to the second recording medium by the second recording circuit and, concurrently, the digital information reproduced by the reproducing circuit is encrypted to produce different encrypted digital information that replaces the encrypted digital information originally recorded in the first recording medium.
