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 may be unlawful to record or play back copyrighted material without the consent of the copyright owner.
Condition Cause
“DISC FULL” is displayed, even though
the possible recording time is not used up.
With the minidisc, there is a maximum number of tracks which can be recorded, regardless of
time. More than 254 tracks cannot be recorded on a disc.
“DISC FULL” is displayed, even though
the number of tracks and recording time
are not at the limit.
When parts of the disc are erased and re-recorded, blank spots are created on the disc. When
recording to such a disc, one track of data is divided and recorded in the blank areas. During
recording, when these divided parts become numerous, the “DISC FULL” message may be
displayed. When a part of 8 seconds or less is created by division, that track cannot be joined
by the JOIN function, and even if it is erased, the remaining usable time on the disc does not
increase. Tracks divided into small pieces may skip when fast forward or fast rewind is done.
The JOIN function sometimes does’t work
The remaining usable time on the disc
doesn’t increase even when tracks are
erased.
The sound skip during fast forward or fast
rewind.
The amount of recorded time on the disc
added to the amount of remaining time
falls shout of the disc’s total possible
recording time.
Minidiscs must have at least 2 seconds of continuous space in order to record. For this rea-
son, the actual recording time of discs with a lot of short blank areas becomes shorter.
