When the number of tracks used reaches
the limit, regardless of the remaining re-
cording time, further recording will be
impossible.
(Maximum number of tracks: 255)
If a MiniDisc has been recorded or ed-
ited 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 record-
ing and editing operations were per-
formed, 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 re-
cording may be less than the remaining time
displayed.
If there are scratches on discs, those sec-
tions will be automatically avoided (no record-
ing will be placed in those sections). There-
fore, the recording time will be reduced.
For MiniDiscs on which repeated record-
ing and editing were performed, some
sounds may be skipped while cueing and
reviewing.
If there are scratches or dust on a
MiniDisc, the track numbers following that
track will be increased by one.
MINIDISC SYSTEM LIMITATIONS
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.
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 op-
erations, some sounds may be
skipped.
A track number can be created in
the middle of a track.
