The recording system in your MD deck has the
limitations described below.
Note, however, that these limitations are due to
the inherent nature of the MD recording system
itself, not to mechanical causes.

“Disc Full!” appears before the MD
has reached the maximum recording
time

When 255 tracks have been recorded on the MD, “Disc
Full!” appears regardless of the total recorded time.
More than 255 tracks cannot be recorded on the MD.
To continue recording, erase unnecessary tracks or use
another recordable MD.

“Disc Full!” appears before the
maximum number of tracks (255) is
reached

Fluctuations in emphasis within tracks are sometimes
interpreted as track intervals, increasing the track count
and causing “Disc Full!” to appear.

“Group Full!” appears in the display

• When the Group Function is on, “Group Full!” may

be displayed if editing is performed. This means
there are insufficient characters for group
management. Delete any unnecessary disc titles,
group titles or other characters.

• Even when the Group Function is off, the group

management information is updated automatically
when Move, Divide and other editing operations are
performed, so “Group Full!” may be displayed.

The remaining recording time does
not increase even after erasing
numerous short tracks

Tracks shorter than 12 seconds* are not counted, so
erasing them may not increase the recording time.

* During Stereo recording.

In Monaural or LP2 stereo mode: about 24 seconds
In LP4 stereo mode: about 48 seconds.

“Impossible” appears when you use
A-B Erase Function or Combine
Function

This happens when you have edited the same track
many times. This is due to a technical limitation of the
MD deck and is not a mechanical error.

The total recorded time and the
remaining time on the MD do not add
up to the maximum recording time

Recording is done in minimum units of 2 seconds*
each, no matter how short the material. The recorded
contents may be shorter than the maximum recording
capacity. Disc space may also be reduced by scratches.

* During Stereo recording.

In Monaural or LP2 stereo mode: about 4 seconds
In LP4 stereo mode: about 8 seconds.

The sound may drop-out while
searching the edited tracks

Tracks created through editing may exhibit sound
dropout during searching because high-speed playback
requires time to search for the position on the disc
when the tracks are not in order.

Track numbers cannot be marked

Even in the Level Synchro Recording, the track
numbers may not be marked at the beginning of the
track:

• if the input signal is below a certain fixed level for

less than 2 seconds between tracks.

• if the input signal is below a certain fixed level for

more than 2 seconds in the middle of the track.

• if you record a track that is 4 seconds or less*.

* During Stereo, Monaural or LP2 stereo recording

mode (In LP4 stereo recording mode: 8 seconds or
less).

Extra tracks are created

When there is a long silence between CD tracks, an
extra track may be created.

The number of tracks on the CD and
the recorded MD is different

When there are short tracks on the CD, track numbers
may not be marked for these tracks, and the number of
tracks recorded on the MD may differ from that of the
CD.
