Rules of Digital Dubbing
The following rules regarding copyright exist for dubbing to MDs from CDs or DATs through digital terminals.
SCMS (Serial Copy Management System)
Minidiscs can record clear sound with low loss of quality from CDs or DATs through each component’s digital input/output terminal. However,
minidiscs are set up so that a disc recorded in this way cannot be recorded onto another minidisc through digital input/output terminals. In other
words, you can not make a copy of a copy. This rule is called SCMS (Serial Copy Management System).
The recorder is designed in compliance with this rule. If you try to make a copy of a copy the error message “SCMS CANNOT COPY” is
displayed, and dubbing can not be done.
It should be noted that it may be unlawful to re-record pre-recorded tapes, records, or discs without the consent of the owner of copyright in the
sound or video recording, broadcast or cable programme and in any literary, dramatic, musical, or artistic work embodied therein.
