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.
To start/stop recording in sync with the source player (Synchro-recording)
You can easily make digital recordings of a digital source on an MD. Before synchro-recording, make connections to the digital source with a digital cable, and insert a recordable MD.

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.

Preventing hearing damage

Precautions

On safety
Do not put any foreign objects in the DC IN 3V jack.
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.

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.

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.

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. 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 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.

Notes on battery

Incorrect battery usage may lead to leakage of battery fluid or bursting battery. To prevent such accidents, observe the following precautions: 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.

Symptom There is no recording on the MD after a recording operation. The lid does not open. Volume cannot be turned up. No sound comes through the headphones/ earphones. An MD is not played from the first track. Playback sound skips. Sound has a lot of static. Cannot find the track marks. The disc cannot edit on other component. Momentary noise is heard.
Cause/Solution The AC power adaptor was unplugged or a power outage occurred during recording.
The battery have been exhausted. , Replace the exhausted battery with new ones. AVLS is on. , Set AVLS to OFF (page 24). The headphones/earphones plug is not firmly connected. , Plug in the plug of the headphones/earphones firmly to i. Volume is too low. , Adjust the volume by pressing VOL +/. Disc playing stopped before it came to the last track. , Press. repeatedly or open and close the lid once to go back to the beginning of the disc, and restart playing after checking the track number in the display. 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. Strong magnetism from a television or such device is interfering with operation. , Move the recorder away from the source of strong magnetism. You pressed X after pressing. or >. , Press X before or pressing. or > (page 29). The component does not support LP2 stereo and LP4 stereo mode. , Edit on other component that support LP2 stereo and LP4 stereo mode. 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 normal stereo or LP2 stereo mode.

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 TrFULL appears even before the disc has reached the maximum recording time (60, 74, or 80 minutes). TrFULL 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. Cause 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.
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 (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. 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 fragmentation of data may cause sound dropout while searching because the tracks are played in higher speed than normal playback.

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.

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.
