Minidisc System Limitations - Sharp MD-MT80W(S) Service Manual

MiniDisc System Limitations

The unit may have the following symptoms while recording or editing. The unit is not out of order.
SYMPTOM
"DISC FULL" or "TOC FULL" appears
even though the MiniDisc still has re-
cording time left.
The remaining recording time does not
increase even though you erased
tracks.
The total of the recorded time and the
remaining time does not match the max-
imum recordable time.
Combine function does not work.
Sound skips in fast reverse/forward.
A track number is created in the middle
of a track.
Troubleshooting
Many potential "problems" can be resolved by the owner without calling a service technician. If something seems to be wrong
with this product, check the following before calling your authorised SHARP dealer or service centre.
PROBLEM
The unit does not turn on.
No sound is heard from the ear-
phones.
When the operation buttons are
pressed, the unit does not respond.
Some sounds are skipped.
The MiniDisc cannot be ejected.
Recording and editing are impossi-
ble.
More than 255 tracks (maximum) cannot be recorded regardless of
the recording time. If the MiniDisc is recorded or edited repeatedly or
if it has scratches (recording 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 re-
cording. For example, a 3-second track uses 2 clusters (approxi-
mately 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 al-
low the combine function.
One track is divided and recorded in separate places on a repeatedly
recorded or edited MiniDisc. Sound may skip.
A track number may be created if there are scratches or dust on the
MiniDisc.
