System limitations
The recording system in your MiniDisc recorder is radically different from those used in
cassette and DAT decks and is characterized by the limitations described below. Note,
however, that these limitations are due to the inherent nature of the MD recording system
itself and not to mechanical causes.
Symptom Cause
“TR FULL” appears
even before the disc
has reached the
maximum recording
time (60, 74, or 80
minutes).
When 254 tracks have been recorded on the disc, “TR FULL”
appears regardless of the total recorded time. More than 254
tracks cannot be recorded on the disc. To continue recording,
erase unnecessary tracks.
“TR FULL” appears
even before the disc
has reached the
maximum track
number or recording
time.
Repeated recording and erasing may cause fragmentation and
scattering of data. Although those scattered data can be read,
each fragment is counted as a track. In this case, the number of
tracks may reach 254 and further recording is not possible. To
continue recording, erase unnecessary tracks.
Track marks cannot be
erased.
The remaining
recording time does
not increase even after
erasing numerous short
tracks.
When the data of a track is fragmented, the track mark of a
fragment under 12 seconds long cannot be erased. You cannot
combine a track recorded in stereo and a track recorded in
monaural; nor can you combine a track recorded with digital
connection and a track recorded with analog connection.
Tracks of under 12 seconds in length are not counted and so
erasing them may not lead to an increase in the recording time.
The total recorded time
and the remaining time
on the disc may not
total the maximum
recording time (60, 74,
or 80 minutes).
Normally, recording is done in minimum units of approximately
2 seconds. When recording is stopped, the last unit of recording
always uses this unit of 2 seconds even if the actual recording is
shorter. Likewise, when recording is restarted after the stop, the
recorder will automatically insert a blank space amounting to 2
seconds before the next recording. (This is to prevent accidental
erasing of a previous track whenever a new recording is started).
Therefore, the actual recording time will decrease whenever a
recording is stopped; a maximum of 6 seconds compared to the
potential recording time for each stop.
The edited tracks may
exhibit sound dropout
during search
operations.
The fragmentation of data may cause sound dropout while
searching because the tracks are played in higher speed than
normal playback.
