Restrictions Imposed by MDs (Minidiscs)
MDs use their own system to record information which is different from conventional cassette tapes and DAT tapes. This system has a
number of restrictions which sometimes give rise to the following symptoms. These symptoms do not, however, indicate that something is
wrong with the product.
Symptom
Cause
“DISC FULL” is displayed even though the
recording time displayed for the MD has not
been used up.
“DISC FULL” is displayed despite sufficient
leeway in track numbers and recording time.
It is sometimes not possible to use the JOIN
function.
The remaining time is not increased even
though tracks are deleted.
The sound is sometimes skipped during rapid
advance or rapid reverse operations.
The recorded time and the remaining time
together do not equal the recording time
displayed for the MD.
Restriction on Copying Digital Material
Due to copyright and other considerations, the following restriction is now in place for MDs onto which the digital signals of CDs have been
copied.
SCMS (Serial Copy Management System)
MDs can digitally record the clear sound of CDs. However, it is now not possible to copy the digital signals of an MD recorded in this way
onto another MD using another unit. In other words, copies of copies cannot be made. This restriction is known as SCMS (Serial Copy
Management System).
This unit is designed to comply with this restriction.
The copyright laws allow recordings to be made for the personal enjoyment of the individual user but they do not allow such recordings to be
used for other any purposes without permission from the holder of the copyrights.
MDs on which CD sound has been recorded using this unit cannot be digitally copied by other units.
The number of tracks which can be recorded on an MD is limited, and this has nothing to
do with the recording time. Track numbers 255 and above cannot be recorded.
When some of the MD recordings are erased and replaced with new recording repeatedly,
empty areas are formed on parts of the disc. When a recording is made on this kind of disc,
the data of a track is divided in bits and pieces among and recorded on these empty areas.
When the number of these divided areas increases, “DISC FULL” may be displayed during
recording. If the data is divided so that some parts are less than 8 seconds in length, it may
not be possible to use the JOIN function to join the track concerned. In addition, the
remaining time will not increase even if these parts are erased. The sound of tracks which
have been divided up in bits and pieces and recorded may break up during rapid advance or
rapid reverse operations.
Recording on an MD is not possible unless there are successive spaces at least 2 seconds in
length. For this reason, a shorter recording time will be displayed for an MD with a large
number of short empty areas.
