ystem limitations
he recording system in your MiniDisc recorder is radically different from those used in
issette and DAT docks and is characterized by the limitations described below. Note,
cnvever, that these limitations are due to the inherent nature of the MD recording system
self and not to mechanical causes.
ymptom
TR FULL" appears even
efore the disc has reached the
jjaximum recording time (60 or
4 minutes).
TR FULL" appears even
■efore the disc has reached the
naximum track number or
ecording time.
(rack marks cannot be erased.
The remaining recording time
loes not increase even after
erasing numerous short tracks.
Cause
When 234 tracks have been recorded on the disc,
"TR FULL" appears regardless of the total
recorded time. More than 254 tracks cannot be
recorcfed 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 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.
The total recorded time and the
remaining time on the disc may
not total the maximum
recording time (60 or 74
minutes).
Recording is done in minimum units of 2 seconds
each, no matter how short the material. Even if
the last unit of recording is less than 2 seconds, it
is counted as a unit of 2 seconds. Then 2 seconds'
space is put before recording starts again to
prevent the last unit of the previous track from
being erased. The contents recorded may thus be
shorter than the maximum recording capacity.
The edited tracks may exhibit
sound dropout during search
operations. The fragmentation of data may cause sound
dropout while searching because the tracks are
played in higher speed than normal playback.
