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.
