Various ways of recording
Long-time recording
(MDLP)
Select each recording mode according to
the recording time that you want.
Stereo recording is possible at 2 times
(LP2) or 4 times (LP4) the normal (SP)
recording time. Monaural recording at 2
times normal recording time is also
possible.
MDs recorded in monaural or
MDLP mode can be played back
only on MD players or recorders
with monaural or MDLP playback
mode.
1 Insert a recordable disc.
2 Press REC MODE repeatedly until
desired recording mode lights up in
the display.
Each time you press the button, A
changes as follows.
3 Press REC.
For other operations on recording, see
“Recording an MD right away!”
(page 13).
z
• If you record in SP, LP2, or LP4 mode using
an externally connected stereo microphone
(not supplied) or other stereo equipment
connected to the LINE IN (OPTICAL) jack,
the recording will be stereo. If you record with
the built-in microphone, the recording will be
monaural (the same sound is recorded to the
left and right channels).
• The recording mode can be changed during
recording pause. When you change the
recording mode, a track mark is automatically
added at that point.
• Audio components that support the LP2 or
LP4 modes are indicated by the or
logo marks.

Notes
• It is recommended that you use the AC power
adaptor (not supplied) for long recordings.
• During monaural recording of a stereo sound
source connected through the digital (optical)
input jack, you can still monitor the recorded
sound in stereo by using headphones/
earphones connected to the i jack.
• When you record in LP4 mode, momentary
noise may be produced on very rare occasions
with certain sound sources. This is because of
the special digital audio compression
technology that enables a recording time 4
times longer than normal. If noise is produced,
it is recommended that you record in SP or
LP2 mode to obtain better sound quality.
Recording from a
stereo microphone
Connect a stereo microphone (ECM-719,
etc.) to the MIC (PLUG IN POWER)
jack. The recorder input automatically
switches to the externally connected
microphone input.
1 Insert a recordable disc and select the
microphone sensitivity.
See “To select microphone
sensitivity” (page 39).
2 Press REC MODE repeatedly until
“SP”, “LP2”, “LP4”, or “MONO”
lights up in the display.
For details on the recording mode, see
“Long-time recording (MDLP)”
(page 18).
3 Press REC.
For other operations on recording, see
“Recording an MD right away!”
(page 13).
z
When using a plug-in power-type microphone,
the microphone can be operated even when its
power switch is turned off since power is
supplied from the recorder itself.
If you are using the optional stereo microphone
ECM-719, set the power switch on the
microphone to OFF to allow the recorder to
provide power to the microphone. It is
recommended that you set the switch on the
microphone to OFF during use.
Notes
• You cannot record through the externally
connected microphone while an optical cable
is connected to the LINE IN (OPTICAL) jack.
The recorder automatically selects the
recorder input in the following order of
priority; optical input, externally connected
microphone input, analog (line) input, and
built-in microphones input.
• The microphone may pick up the operating
sound of the recorder itself (such as the sound
of the motor). Use the microphone away from
the recorder in such cases. Please note that the
sound of recorder operations may be picked
up if the microphone that you use has a short
connector.

Recording from externally connected equipment
The LINE IN (OPTICAL) jack of this recorder works as both digital and analog input
jacks. Connect the recorder to a CD player or a cassette recorder using either digital
(optical) input or analog (line) input. To record, see “Recording with digital (optical) input
(Digital Recording)” (page 21) to record using digital (optical) input and “Recording from
a TV or radio (Analog Recording)” (page 22) to record using analog (line) input.
LINE IN (OPTICAL) jack is for both digital and analog input.
The recorder automatically recognizes the type of line cable and switches to digital or analog input.
Difference between digital (optical) and analog (line) inputs
Note
Track marks may be copied incorrectly:
• when you record from some CD players or multi disc players using digital (optical) input.
• when the source is in shuffle or program play mode while recording using digital (optical) input. In
this case, play the source in normal play mode.
• when programs with audio that is digitally broadcast (e.g., digital TV) are recorded.

closing of the lid) occurs for one hour, the
recorder turns off. For this reason, the next
time you start playback or do another
operation, the recorder will not respond
quickly. The unit, however, will return to
quick mode afterwards.

jack.
On power sources
• Use LR6 (size AA) batteries, house current, or
car battery.
• 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 (an optional AC power adaptor, dry
batteries, or car battery cord). To remove the
AC power adaptor (not supplied) 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 (not
supplied). Heat build-up in the recorder may
cause malfunction or damage.
• Never carry the recorder together with a hard
object within the supplied carrying pouch.
Friction with the object may cause flacking or
scratching on the recorder’s painted surface.
On the headphones/earphones
Road safety
Do not use the 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.
Preventing hearing damage
Avoid using the 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.
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.
• Attach the supplied MD label only in the
space designated for it on the disc. Do not
stick it on any other disc surface.
Notes on batteries
Incorrect battery usage may lead to leakage of
battery fluid or bursting batteries. To prevent
such accidents, observe the following
precautions:
• Insert the + and – poles of the batteries
correctly.
• Do not try to recharge dry batteries.
• 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.

45
Note on mechanical noise
The recorder gives off mechanical noise while
operating, which is caused by the power-saving
system of the recorder and it is not a problem.
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.
• To obtain the best sound quality, use a dry
cloth to wipe the plug of the headphones/
earphones. Dirty plug may cause sound
distortion or intermittent breaks in the sound.

Troubleshooting and explanations
Troubleshooting
If a problem occurs during recorder operation, follow the steps described below before
consulting the nearest Sony dealer. If any messages appear, it is recommended to take
notes.
1 Check to see if the problem is listed in, “Troubleshooting” (page 48).
Check “Messages” (page 53) for the problem as well.
2 If after step 1 you still cannot solve the problem, consult your nearest Sony dealer.
While recording
Symptom Cause/Remedy
Recording cannot be
done correctly.
• Audio sources may not be securely connected.
, Disconnect the audio sources once and connect them again
(pages 21, 22).
• There is no digital signal from the portable CD player.
, When recording digitally from a portable CD player, use
the AC power adaptor and disable the anti-skip function
(such as ESP) on the CD player (page 21).
• The analog recording was made using a connecting cord with
an attenuator.
, Use a connecting cord without an attenuator (page 22).
• The power sources was disconnected or a power outage
occurred during recording.
, The recording result is not recorded on the disc. Make
recording again.
• The premastered MD is inserted.
, Replace to the recordable MD.
• The remaining recordable time on the disc is 12 seconds or
less (“DISC FULL” appears).
, Replace the disc.
Momentary noise is
heard when recording.
• Due to the special digital audio compression technology used
in LP4 stereo mode, momentary noise may occur on very rare
occasions with certain sound sources.
, Record in SP or LP2 mode (page 18).
The lid does not open
after recording.
• The lid does not open until “TOC Edit” disappears in the
display.

49
“TR FULL” appears
even before the disc
has reached the
maximum recording
time (60, 74, or 80
minutes) and the
recording cannot be
done.
• This is due to the MiniDisc system limitation.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.
The remaining
recording time does
not increase even after
erasing numerous
short tracks.
• This is due to the MiniDisc system limitation. Tracks of under
12 seconds, 24 seconds, 48 seconds in length are not counted
and so erasing them may not lead to an increase in the
recording time.
The total recorded
time and the remaining
time on the disc may
not total the maximum
recording time (60, 74,
or 80 minutes).
• This is due to the MiniDisc system limitation. Normally,
recording is done in minimum units of approximately 2
seconds (in stereo), 4 seconds (in LP2 stereo mode or
monaural mode), or 8 seconds (in LP4 stereo mode). When
recording is stopped, the last unit of recording always uses this
unit of 2 seconds, 4 seconds, or 8 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, 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; a maximum of 6 seconds, 12 seconds, or
24 seconds compared to the potential recording time for each
stop.
“TR FULL” appears
even before the disc
has reached the
maximum track
number or recording
time.
• This is due to the MiniDisc system limitation. 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.
, To continue recording, erase unnecessary tracks.
Symptom Cause/Remedy
Troubleshooting and explanations

While playing
Symptom Cause/Remedy
An MD is not
played normally.
• Repeat play is selected.
, Change back to the normal play (page 27).
• Playback mode is changed.
, Change back to the normal play (page 27).
An MD is not
played from the
first track.
• Disc playing stopped before it came to the last track.
, Press N • PLAY for 2 seconds or more to start playing.
Playback sound
skips.
• The recorder is placed where it receives continuous vibration.
, Put the recorder on a stable place.
• A very short track may cause sound to skip.
, Try not to create a track under one second long.
Sound has a lot of
static.
• Strong magnetism from a television or such device is interfering
with operation.
, Move the recorder away from the source of strong magnetism.
The volume of the
recorded track is
low.
• The track was recorded in analog mode (in digital mode, the
recording level is automatically set to the same level as that of the
sound source). Or you used a connecting cord with an attenuator
(such as an optional RK-G128, RK-G134, etc.) .
, Use a correct connecting cord (such as RK-G129, RK-G136,
etc.).
No sound comes
through the
headphones/
earphones.
• The headphones/earphones plug is not firmly connected.
, Plug in the plug of the headphones/earphones firmly to the i
jack.
• The plug is dirty.
, Clean the plug.
The recorder skips
several tracks
ahead or behind
whenever you
press the . •
REVIEW • AMS
or > • CUE •
AMS button.
• The GROUP button has been pressed and is flashing in the
display.
, The recorder returns to normal if no operation is made for 5
seconds.
The edited tracks
may exhibit sound
dropout during
search operations.
• This occurs due to the MiniDisc system limitation. The
fragmentation of data may cause sound dropout while searching
because the tracks are played in higher speed than normal
playback.

51
While Editing
There is no R-
channel sound
output when
playing a track
recorded from a
cassette deck or
through an
amplifier, or when
listening to sound
from a cassette
deck or amplifier.
• There is no R-channel output if the cassette deck or an amplifier is
connected with a monaural cord.
, Make sure to use a stereo connecting cord. If, however, the
connected equipment is monaural, there will be no R-channel
sound output even with a stereo connecting cord.
The optional foot
control unit does
not work properly.
• The recorder is not set for foot control unit use.
, Set “FOOT SW” in the menu to “SW ON” (page 40).
Symptom Cause/Remedy
The lid does not
open.
• The power sources have been disconnected during recording or
editing, or the battery have been exhausted.
, Set the power sources again, or replace the exhausted battery
with new ones.
Editing cannot be
done.
• The power source has been disconnected or a power outage has
occurred during editing.
, The editing done to that point is not saved to the disc. Do the
editing operation again.
Track marks
cannot be erased.
• This is due to the MiniDisc system limitations. When the data of a
track is fragmented, the track mark of a fragment under 12 seconds
long (recorded in stereo), 24 seconds long (recorded in LP2 stereo
mode or monaural mode), or 48 seconds long (recorded in LP4
stereo mode) 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.
The disc cannot
edit on other
component.
• The component does not support MDLP.
, Edit on other component that support MDLP.
Symptom Cause/Remedy

• While using a disc without group setting, an attempt was made to
select some group-related menu.
, Use a disc with group setting.
A track cannot be
recorded to a new
group. A new
group cannot be
created.
• This is due to the MiniDisc system limitations. If the total number
of characters for the disc can store exceeds approximately 1,700, a
new group cannot be created even though group mode is on. It is
also impossible to make group settings at this time.
Symptom Cause/Remedy

Explanations
About the DSP TYPE-S for ATRAC/ATRAC3
This recorder supports DSP TYPE-S, a specification for high-level Sony MiniDisc decks
equipped with digital signal processors (DSP). This specification allows the recorder to produce
high-quality sound from tracks recorded in MDLP mode. Since it retains DSP TYPE-R support,
the recorder produces superior results during recording or playback in SP (normal stereo) mode.
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 on the left column), 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.
The meaning of “no sound”
“No sound” describes a recorder condition in which the input level is about 4.8 mV during
analog input or less than –89 dB during optical (digital) input (with 0 dB as full bit (the
maximum recordable level for a MiniDisc)).
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 file on a
diskette.
BA
A — User TOC area
Contains the order and start/end points of
the music.
B — Music Data

57
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.
Note on digital recording
This recorder uses the Serial Copy Management System, which allows only first-generation digital
copies to be made from premastered software. You can only make copies from a home-recorded MD by
using the analog (line out) connections.
If you have any questions or problems concerning your recorder, please consult your nearest Sony
dealer. (If a trouble occurred when the disc was in the recorder, we recommend that the disc be left in
the recorder when you consult your Sony dealer so that the cause of trouble may be better understood.)
