MZ-R30 Operating Instructions
Cannot find the track marks.
Charging the rechargeable
battery does not start.
The clock loses time or the
display flashes.
The recording date was not
stamped onto the disc.

System limitations

The recording system in your MiniDisc recorder is radically different from those used in cassette and DAT decks
and is characterized by the limitations described below. Note, however, that these limitations are due to the
inherent nature of the MD recording system itself and not to mechanical causes.
Symptom
"TR FULL" appears even before the disc has
reached the maximum recording time (60 or 74
minutes).
"TR FULL" appears even before the disc has
reached the maximum track number or recording
time.
Track marks cannot be erased.
The remaining recording time does not increase
even after erasing numerous short tracks.
The total recorded time and the remaining time
on the disc may not total the maximum recording
time (60 or 74 minutes).
The edited tracks may exhibit sound drop out
during search operations.

Cause
When 254 tracks have been recorded on the disc, "TR FULL"
appears regardless of the total recorded time. More than 254
tracks cannot be recorded on the disc. To continue recording,
erase unnecessary tracks.
Repeating 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.
Tracks of under 12 seconds in length are not counted and so
erasing them may not lead to an increase in the recording
time.
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 fragmentation of data may cause sound dropout while
searching because the tracks are played in higher speed than
normal playback.
