Symptom
Stereo sound is heard
in the headphones/
earphones while
recording in monaural.
Momentary noise is
heard when recording.
The lid does not open
after recording.
"TRACK FULL"
appears even before
the disc has reached
the maximum
recording time and the
recording cannot be
done.
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).
"TRACK FULL"
appears even before
the disc has reached
the maximum track
number or recording
time.

Cause/Remedy
• This is normal. During digital recording, the sound will be stereo in
the headphones/earphones, even though the recorded sound is
monaural.
• Due to the special digital audio compression technology used in
LP4 stereo mode, momentary noise may occur on very rare
occasions with certain sound sources.
, Record in SP or LP2 mode.
• The lid does not open until "SYSTEM FILE WRITING" disappears
in the display.
• This is due to the MiniDisc system limitation. When 254 tracks (on
a standard disc) or 2,047 tracks (on a disc used in Hi-MD mode)
have been recorded on the disc, "TRACK FULL" appears regardless
of the total recorded time. More than 254 or 2,047 tracks cannot be
recorded on the disc.
, To continue recording, erase unnecessary tracks.
• This is due to the MiniDisc system limitation (in MD mode only).
Tracks of under 12 seconds (in SP stereo), 24 seconds (in LP2 stereo
mode or monaural), or 48 seconds (in LP4 stereo mode) in length
are not counted and so erasing them may not lead to an increase in
the recording time.
• This is due to the MiniDisc system limitation (in MD mode only).
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.
• This is due to the MiniDisc system limitation. 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 (on a
standard disc) or 2,047 (on a disc used in Hi-MD mode) and further
recording is not possible.
, To continue recording, erase unnecessary tracks.
