mum recordable time.
Combine function does not work.

of a track.

More than 255 tracks (maximum) cannot be recorded regardless of the re-
cording time.
If the MiniDisc is recorded or edited repeatedly or if it has scratches (record-
ing skips scratched parts), you may not be able to record the maximum
tracks above.
The unit does not count non-recorded portions that last 12 or fewer seconds
to display the remaining recording time. The time may not increase even if
you erase short tracks.
One cluster (approximately 2 seconds) is the minimum unit for recording.
For example, a 3-second track uses 2 clusters (approximately 4 seconds).
Therefore, the actual recordable time may be shorter than the displayed
time.
A MiniDisc on which recording and editing are repeated may not allow the
combine function.
One track is divided and recorded in separate places on a repeatedly re-
corded or edited MiniDisc.
Sound may skip.
A track number may be created if there are scratches or dust on the MiniDisc.
