Various ways of recording

Two ways of connecting to a sound source

The input 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 an MD right away!” (page 10) to record using

digital (optical) input, and “Recording with analog input (line cable required)” (page 16) to

record using analog (line) 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 recording BS or CS programs through digital (optical) input.

recorded digitally on the disc.

1Insert a recordable MD and start

recording.

For recording operations, see

“Recording an MD right away!”

(page 10). To record from a portable

CD player, set the CD player to pause

and then start recording.

digital and analog input

The recorder automatically recognizes the type

of line cable and switches to digital or analog

input.

Note

A track mark is added at the point where you

press X again to resume recording while

pausing recording; thus the track will be

counted as a new track.

Recording for long

times

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

recording time.

MDs recorded in monaural, LP2 or

LP4 mode can be played back only

on MD players or recorders with

monaural, LP2 or LP4 playback

mode.

•Audio components that support the LP2 or

LP4 modes are indicated by the or

logo marks.

•Once you set, the recorder keeps its recording

mode when you record the next time.

•You can achieve high sound quality and rich

tones when recording in normal stereo (or

monaural) thanks to the newly developed DSP

TYPE-R for ATRAC (Adaptive TRansform

Acoustic Coding).

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.

Notes

•You cannot change the recording mode while

recording.

•It is recommended that you use the AC power

adaptor for long recordings.

•If you try to play an MD recorded in LP2

stereo or LP4 stereo on a player/recorder that

is not support these modes, playback will not

start and “LP:” will appear on the display.

•Sound recorded through digital (optical) input

can be monitored in stereo through

headphones/earphones, etc.

•When you record in LP4 stereo 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 normal stereo or LP2 stereo mode to

obtain better sound quality.

recorder stops automatically.

•For longer recording, follow steps 1 to 3 of

“Recording for long times” (page 16) to select

the recording mode, and then start the

procedure of synchro-recording.

Notes

•Do not change the “SYNC-R” setting while

recording. Recording may not be done

properly.

•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

Using Auto Time Stamp to add

track marks while recording

When the elapsed recording time

exceeds the time interval for Auto

Time Stamp:

From that point the recorder adds a track

mark whenever the time interval has

elapsed.

Example: 8 minutes of recording has

already been done when an Auto Time

Stamp time interval of 5 minutes is set.

A track mark will be added at the 13-

minute point (after the start of recording)

and after each 5-minute interval

thereafter.

When the time interval set for Auto

Time Stamp exceeds the elapsed

recording time:

The recorder adds a track mark when the

set Auto Time Stamp time interval has

elapsed.

Example: 3 minutes of recording has

already been done when an Auto Time

Stamp time interval of 5 minutes is set

A track mark will be added at the 5-

minute point (after the start of recording)

and after each 5-minute interval

thereafter.

Notes

•Automatic track marking by Auto Time Stamp

starts when you add a normal track mark to

the disc (i.e., by pressing T MARK or X,

etc.).

•The setting will be lost when the recording

stopped.

Precautions

On safety

Do not put any foreign objects in the DC IN 3V

jack.

On power sources

•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.

•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

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/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.

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.

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.

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 plugs of the headphones/

earphones. Dirty plugs may cause sound

distortion or intermittent breaks in the sound.

operating, which is caused by the power-saving

system of the recorder and it is not a problem.

To protect a recorded MD

To record-protect an MD, slide open the tab at

the side of the MD. In this position, the MD

cannot be recorded or edited. To record again,

slide the tab back so the tab is visible.

Note on digital recording

This recorder uses the Serial Copy

Management System, which allows only first-

generation digital copies to be made from

copies from a home-recorded MD by using the

analog connections.

Note on maintenance

Clean the terminal periodically with a cotton

swab or a soft cloth as illustrated below.

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.)

Symptom Cause/Solution

35

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.

Track marks cannot be

erased.

The remaining

recording time does

not increase even after

erasing numerous

short tracks.

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 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

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).

Normally, recording is done in minimum units of approximately

2 seconds (in stereo), 4 seconds (in LP2 stereo mode or

monaural), 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 by

a maximum of 6 seconds, 12 seconds, or 24 seconds.

The edited tracks may

exhibit sound dropout

during search

operations.

The fragmentation of data may cause sound dropout while

searching because the tracks are played in higher speed than

normal playback.

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

file on a diskette.
