noise is produced, it is recommended that you

• You can achieve high sound quality and rich
tones when recording in normal stereo (or

TYPE-R for ATRAC (Adaptive TRansform

What is the newly developed DSP
TYPE-R for ATRAC?
“TYPE-R” is a high-level Sony specification
used in the Digital Signal Processor (DSP),
which is heart of the MiniDisc sound. This
technology gives the MiniDisc recorder twice
the signal processing capability as previous
MiniDisc Walkman models, producing a
sound quality close to that of MiniDisc decks.

Additional information
Preventing hearing damage
Avoid using headphones/earphones 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.
Precautions
On safety
Do not put any foreign objects in the DC IN 3V
jack.
Caring for others
On power sources
Keep the volume at a moderate level. This will
allow you to hear outside sounds and to be
considerate of the people around you.
• Use house current or LR6 (size AA) battery.
• For use in your house: Use the AC power
adaptor. Do not use any other AC power
adaptor than the ones designated for this
recorder since it may cause the recorder to
malfunction.
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.
• Attach the supplied MD label only in the
space designated for it on the disc. Do not
stick it on any other disc surface.
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 or dry battery). To
remove the AC power adaptor from the wall
outlet, grasp the adaptor plug itself; never pull
the cord.
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.
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.
• 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.
• To obtain the best sound quality, use a dry
cloth to wipe the plugs of the headphones/
earphones. Dirty plugs may cause sound
distortion or intermittent breaks in the sound.
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.
Notes on battery
Incorrect battery usage may lead to leakage of
battery fluid or bursting battery. To prevent
such accidents, observe the following
precautions:
On the headphones/earphones
Road safety
Do not use headphones/earphones 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.
• Install the + and – poles of the battery
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 battery.
• 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
“TrFULL” appears
even before the disc
has reached the
maximum recording
time (60, 74, or 80
minutes).
When 254 tracks have been recorded on the disc, “TrFULL”
appears regardless of the total recorded time. More than 254
tracks cannot be recorded on the disc. To continue recording,
erase unnecessary tracks.
“TrFULL” appears
even before the disc
has reached the
maximum track
number or recording
time.
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.

You cannot combine tracks recorded in different recording
modes, e.g., 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, 24 seconds, or 48 seconds in length

in the recording time.

recorder will automatically insert a blank space amounting to 2
seconds, 4 seconds, or 8 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 by

Explanations
How the MiniDisc got so small
The 2.5-inch MiniDisc, encased in a plastic
cartridge that looks like a 3.5-inch diskette,
uses a new digital audio compression
technology called ATRAC (Adaptive
TRansform Acoustic Coding). To store more
sound in less space, ATRAC 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
