Abstract:
1. A reproducing apparatus for moving main data that has been subjected to reproduction-restrictive coding from a first recording medium where the main data is recorded to a second recording medium, the apparatus comprising: storing means for storing a key to be used for decoding a code that restricts reproduction of the main data; input means for receiving the main data from the first recording medium; judging means for judging whether the main data received by the input means can be decoded by using the key that is stored in the storing means; first output means for outputting the main data received by the input means to the second recording medium; second output means for informing the first recording medium of permission or prohibition of movement of the main data and completion of the movement of the main data; and control means for causing the first output means to output the main data received by the input means to the second recording medium when the judging means judges that the main data can be decoded, and for prohibiting the first output means from outputting the main data received by the input means to the second recording medium when the judging means judges that the main data cannot be decoded, wherein the control means causes the second output means to inform the first recording medium of permission of movement of the main data and thereby causes output of the main data when the judging means judges that the main data can be decoded, and causes the second output means to inform the first recording medium of completion of the movement and thereby causes erasure of the main data from the first recording medium when the movement of the main data is completed.
