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) and
the recording cannot be
done. 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 (recorded in SP stereo),
24 seconds long (recorded in LP2 stereo mode or monaural
mode), or 48 seconds long (recorded in LP4 stereo mode)
cannot be erased. You cannot combine tracks recorded in
different recording modes, e.g., 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, 24 seconds, or 48 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 (in SP stereo), 4 seconds (in LP2
stereo mode or monaural), or 8 seconds (in LP4 stereo
mode). When recording is stopped, the last unit of
recording always uses this unit of 2 seconds, 4 seconds, or
8 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,
4 seconds, or 8 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 by a
maximum of 6 seconds, 12 seconds, or 24 seconds.
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.
