TROUBLESHOOTING
When the number of tracks used
reaches the limit, regardless of the
remaining recording time, further
recording will be impossible.
(Maximum number of tracks: 254)
If a MiniDisc has been recorded or
edited repeatedly or if a MiniDisc has
scratches on it, it may not be possible
to record the maximum number of
tracks on it.
If there are scratches on a disc, the
unit will automatically avoid recording
in those areas. The recording time will
be reduced.
When the remaining recording time of
a disc is displayed, short tracks less
than 12 seconds long may not be
included in the total.
For MiniDiscs on which repeated
recording and editing operations were
performed, the COMBINE function
may not work.
A cluster (about 2 seconds) is
normally the minimum unit of
recording. So, even if a track is less
than 2 seconds long, it will use about
2 seconds of space on the disc.
Therefore, the time actually available
for recording may be less than the
remaining time displayed.
If there are scratches on discs, those
sections will be automatically avoided
(no recording will be placed in those
sections). Therefore, the recording
time will be reduced.
For MiniDiscs on which repeated
recording and editing were performed,
some sounds may be skipped whilst
cueing and reviewing.
If there are scratches or dust on a
MiniDisc, the track numbers following
that track will be increased by one.
Even if the maximum recording
time of a MiniDisc has not been
reached, “DISC FULL” or “TOC
FULL” may be displayed.
Even if the number of tracks and
the recording time have not
reached the limit, “DISC FULL” may
be displayed.
Even if several short tracks are
erased, the remaining recording
time may not show an increase.
Two tracks may not be combined in
editing.
The total of the recorded time and
time remaining on a disc may not
add up to the maximum possible
recording time.
When recorded tracks are played
back using the cue and review
operations, some sounds may be
skipped.
A track number can be created in
the middle of a track.
MiniDiscs are recorded using a different system than is used for cassette tapes or DAT
recordings. Therefore, the following conditions may be encountered, depending on how
the disc has been recorded or edited. These are due to system limitations, and should
be considered normal.

NOTES ON SCHEMATIC DIAGRAM
• Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
