synchro-recording.
• Even when there is no recorded sound on the sound source, there may be
cases when recording does not pause automatically during synchro-recording
due to the noise level emitted from the sound source.
• If a silent portion is encountered for 2 seconds or more during synchro-
recording, a new track mark is automatically added at the point where the
silent portion ends.
• Synchro-recording cannot be done if the connecting cord is not an optical

Precautions
On safety
Do not put any foreign objects in the DC IN 3V jack.
On power sources
• Use house current, nickel cadmium rechargeable battery, LR6 (size AA)
battery, or car battery.
• For use in your house: Use the AC power adaptor supplied with this recorder.
Do not use any other AC power adaptor since it may cause the recorder to
malfunction.
Polarity of the
plug
• The recorder is not disconnected from the AC power source (mains) as long
as it is connected to the wall outlet, even if the recorder itself has been turned
off.
• If you are not going to use this recorder for a long time, be sure to disconnect
the power supply (AC power adaptor, dry battery, rechargeable battery, or car
battery cord). To remove the AC power adaptor from the wall outlet, grasp
the adaptor plug itself; never pull the cord.
On heat build-up
Heat may build up in the recorder if it is used for an extended period of time.
In this case, leave the recorder turned off until it cools down.
On installation
• Never use the recorder where it will be subjected to extremes of light,
temperature, moisture or vibration.
• Never wrap the recorder in anything when it is being used with the AC power
adaptor. Heat build-up in the recorder may cause malfunction or damage.

On the headphones
Road safety
Do not use headphones while driving, cycling, or operating any motorized
vehicle. It may create a traffic hazard and is illegal in many areas. It can also be
potentially dangerous to play your recorder at high volume while walking,
especially at pedestrian crossings. You should exercise extreme caution or
discontinue use in potentially hazardous situations.
Preventing hearing damage
Avoid using headphones at high volume. Hearing experts advise against
continuous, loud and extended play. If you experience a ringing in your ears,
reduce the volume or discontinue use.
Caring for others
Keep the volume at a moderate level. This will allow you to hear outside
sounds and to be considerate of the people around you.
On the MiniDisc cartridge
• When carrying or storing the MiniDisc, keep it in its case.
• Do not break open the shutter.
• Do not place the cartridge where it will be subject to light, extreme
temperatures, moisture or dust.
On cleaning
• Clean the recorder casing with a soft cloth slightly moistened with water or a
mild detergent solution. Do not use any type of abrasive pad, scouring
powder or solvent such as alcohol or benzene as it may mar the finish of the
casing.
• Wipe the disc cartridge with a dry cloth to remove dirt.
• Dust on the lens may prevent the unit from operating properly. Be sure to
close the disc compartment lid after inserting or ejecting an MD.
Notes on batteries
Incorrect battery usage may lead to leakage of battery fluid or bursting
batteries. To prevent such accidents, observe the following precautions:
• Install the + and – poles of the batteries correctly.
• Do not try to recharge dry battery.
• When the recorder is not to be used for a long time, be sure to remove the
batteries.
• If a battery leak should develop, carefully and thoroughly wipe away battery
fluid from the battery compartment before inserting new ones.

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 Cause
“TR FULL”
appears even
before the disc
has reached the
maximum
recording time
(60, 74, or 80
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.
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.
Repeated 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. You cannot combine a track
recorded in stereo and a track recorded in
monaural; nor can you combine a track recorded
with digital connection and a track recorded
with analog connection.
Tracks of under 12 seconds in length are not
counted and so erasing them may not lead to an
increase in the recording time.
63
Page 64
Symptom Cause
The total
recorded time
and the
remaining time
on the disc may
not total the
maximum
recording time
(60, 74, or 80
minutes).
The edited tracks
may exhibit
sound dropout
during search
operations.
Normally, recording is done in minimum units
of approximately 2 seconds. When recording is
stopped, the last unit of recording always uses
this unit of 2 seconds even if the actual
recording is shorter. Likewise, when recording is
restarted after the stop, the recorder will
automatically insert a blank space amounting to
2 seconds before the next recording. (This is to
prevent accidental erasing of a previous track
whenever a new recording is started). Therefore,
the actual recording time will decrease
whenever a recording is stopped; a maximum of
6 seconds compared to the potential recording
time for each stop.
The fragmentation of data may cause sound
dropout while searching because the tracks are
played in higher speed than normal playback.

What is an MD?
How MiniDisc works
MiniDisc (MD) comes in two
types: premastered (prerecorded)
and recordable (blank).
Premastered MDs, recorded at
music studios, can be played back
almost endlessly. However, they
can’t be recorded on or over like
cassette tapes. To record, you must
use a “recordable MD”.
Premastered MDs
Premastered MDs are recorded
and played like regular CDs. A
laser beam focuses on the pits in
the surface of the MD and reflects
the information back to the lens in
the recorder. The recorder then
decodes the signals and plays
them back as music.
How the MiniDisc got so small
The 2.5-inch MiniDisc, encased in
a plastic cartridge that looks like a
3.5-inch diskette (see illustration
above), uses a new digital audio
compression technology called
ATRAC (Adaptive TRansform
Acoustic Coding). To store more
sound in less space, ATRAC
Recordable MDs
Recordable MDs, which use
magneto-optical (MO)
technology, can be recorded again
and again. The laser inside the
recorder applies heat to the MD,
demagnetizing the magnetic layer
of the MD. The recorder then
applies a magnetic field to the
layer. This magnetic field
corresponds exactly to the audio
signals generated by the connected
source. (The north and south
polarities equate to digital “1” and
“0”.) The demagnetized MD
adopts the polarity of the magnetic
field, resulting in a recorded MD.
extracts and encodes only those
frequency components actually
audible to the human ear.

Quick Random Access
Like CDs, MDs offer
instantaneous random access to
the beginning of any music track.
Premastered MDs are recorded
with location addresses
corresponding to each music
selection.
Recordable MDs are
manufactured with a “User
TOC Area” to contain the order of
the music. The TOC (Table of
Contents) system is similar to the
“directory management system”
of floppy disks. In other words,
starting and ending addresses for
all music tracks recorded on the
disc are stored in this area. This
lets you randomly access the
beginning of any track as soon as
you enter the track number
(AMS), as well as label the
location with a track name as you
would a file on a diskette.
User TOC Area
Contains the order and start/end
points of the music.
Shock-Resistant Memory
One major drawback of optical
read systems is that they can skip
or mute when subjected to
vibration. The MD system
resolves this problem by using a
buffer memory that stores audio
data.
