Handling MDs
The MD is enclosed in a cartridge to protect the disc from
debris or fingerprints and to make it easy to handle.
However, the presence of debris or a warped cartridge
may inhibit the disc from operating properly. To ensure
that you can always listen to the highest quality music,
follow the precautions below:
• Do not touch the internal disc directly. Forcing the
shutter open may damage the internal disc.
• Be sure to stick the labels supplied with the MD to the
appropriate positions. The shape of the labels may vary
depending on the MD brand.
Where to keep the MDs
Do not place the cartridge where it may be exposed to
direct sunlight or extremely high heat and humidity.
Regular maintenance
Wipe dust and debris from the surface of the cartridge
with a dry cloth.
System limitations
The recording system in your deck 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.
“Disc Full” appears in the display even before
the MD has reached the maximum recording
time
When 255 tracks have been recorded to the MD,
“Disc Full” appears regardless of the total recorded time.
More than 255 tracks cannot be recorded to the MD. To
continue recording, erase unnecessary tracks or use
another recordable MD.
“Disc Full” appears before the maximum
number of tracks is reached
Fluctuations in emphasis within tracks are sometimes
interpreted as track intervals, incrementing the track count
and causing “Disc Full” to appear.
The remaining recording time does not
increase even after erasing numerous short
tracks
Tracks under 12 seconds* in length are not counted and so
erasing them may not lead to an increase in the recording
time.
* During stereo recording.
In MONO or LP2 mode: about 24 seconds
In LP4 mode: about 48 seconds
The total recorded time and the remaining
recordable time on the MD may not total the
maximum recording time
Recording is done in minimum units of two seconds*
each, no matter how short the material is. The contents
recorded may thus be shorter than the maximum recording
capacity. Disc space may also be further reduced by
scratches.
* During stereo recording.
In MONO or LP2 mode: about 4 seconds
In LP4 mode: about 8 seconds
Limitations when recording over an existing
track
• The correct remaining recordable time may not be
displayed.
• You may find it impossible to record over a track if that
track has been recorded over several times already. If
this happens, erase the track (see page 31).
• The remaining recordable time may be shortened out of
proportion to the total recorded time.
• Recording over a track to eliminate noise is not
recommended since this may shorten the duration of the
track.
• You may find it impossible to name a track while
recording over an existing track.
Tracks created through editing may exhibit
sound dropout as you are searching for a point
while monitoring the sound.
Some tracks cannot be combined with others
Tracks may not be combined if they have been edited.
Track numbers are not marked correctly
Incorrect assignment or marking of track numbers may
result when CD tracks are divided into several smaller
tracks during digital recording. Also, when the Automatic
Track Marking is activated during recording, track
numbers may not be marked as in the original, depending
on the program source.
“TOC Reading” appears for a long time
If the inserted recordable MD is brand new, “TOC
Reading” appears in the display longer than for MDs that
have already been used.
