System Limitations - Sony Walkman MZ-S1 Mode D'emploi

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
"TrFULL" appears even
before the disc has reached
the maximum recording
time (60, 74, or 80 minutes).
"TrFULL" appears even
before the disc has reached
the maximum track number
or recording time.
Track marks cannot be
erased.
The remaining recording
time does not increase even
after erasing numerous short
tracks.
The total recorded time and
the remaining time on the
disc may not total the
maximum recording time
(60, 74, or 80 minutes).
The edited tracks may
exhibit sound dropout
during search operations.

Cause
When 254 tracks have been recorded on the disc,
"TrFULL" appears regardless of the total recorded time.
More than 254 tracks cannot be recorded on the disc. To
continue recording, erase unnecessary tracks.
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.
When the data of a track is fragmented, the track mark of a
fragment under 12 seconds long (recorded in stereo), 24
seconds long (recorded in monaural or LP2 mode), or 48
seconds long (recorded in LP4 mode) cannot be erased.
You cannot combine a track recorded in different
recording mode, 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.
Normally, recording is done in minimum units of
approximately 2 seconds (in stereo), 4 seconds (in
monaural or LP2 mode), or 8 seconds (in LP4 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 fragmentation of data may cause sound dropout while
searching because the tracks are played in higher speed
than normal playback.
