About the DSP TYPE-R for ATRAC
TYPE-R is a high-level Sony specification used in the Digital Signal Processor (DSP), which is the 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. This unit supports the TYPE-R function only during recording or playback in normal stereo (or monaural) mode. It does not support this function in MDLP mode, or during the checking out of audio data from the computer in normal stereo (or monaural) mode using OpenMG Jukebox.
The pause function cannot be turned on or off manually during synchro-recording. Press x to stop recording. Do not change 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 approximately 2 seconds during synchrorecording from a sound source other than a CD or an MD, a new track mark is automatically added at the point where the silent portion ends. You cannot change the recording mode during recording. Saving or Edit flashes while data of the recording (the tracks start and end points, etc.) is being recorded. Do not move the recorder or disconnect the power source while the indication is flashing in the display. The lid does not open until Edit disappears in the display. If the power supply is disrupted (i.e. the battery is removed or becomes exhausted or the AC power adaptor is disconnected) during a recording or editing operation, or while Edit appears in the display, then it will not be possible to open the lid until power is restored. You can make a digital recording only from an optical type output. When recording from a portable CD player, set the CD player to pause, and then do the recording procedure on the recorder. Note the following when recording from a portable CD player: Some portable CD players may not be capable of digital out when the AC power adaptor is disconnected. If this is the case, connect the AC power adaptor to the portable CD player and use it on AC power as the power source. On some portable CD players, optical output may not be possible when using an anti-skip function (e.g., ESP* or GPROTECTION). If this is the case, turn off the anti-skip function.
For longer recording, follow step 1 of Longtime recording (MDLP) (page 26) to select the recording mode, and then start the procedure of synchro-recording. 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. The recording level is adjusted automatically. To adjust the level manually, see Adjusting the recording level manually (Manual Recording) (page 31). You can monitor the sound during recording. Connect the headphones/earphones to i and adjust the volume by pressing VOL +/. This does not affect the recording level.

A long beep sounds in the headphones/ earphones. After you press x on the recorder to stop, the recorder will automatically turn off in about 10 seconds (when using the dry battery) or about 3 minutes (when using the AC power adaptor). Playback starts from the point you last stopped playing. To start playback from the beginning of the first track, press and hold N for 2 seconds or more on the recorder.

If the play does not start
Make sure the recorder is not locked (page 15, 47).
Suppressing the skips of the sound (G-PROTECTION)
The G-PROTECTION function was developed to provide a higher level of shock resistance than that of existing players.
The playback sound may skip if: the recorder receives stronger continuous shock. a dirty or scratched MiniDisc is played.
The playback mode will switch automatically (stereo, LP2 stereo, LP4 stereo, or monaural). To play only the tracks in a certain group, see Using the group function (Group Mode) (page 33).
Various ways of recording
Note on digital and analog recording (Digital input and analog input)
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! (Synchro-recording) (page 16) to record using digital (optical) input, and Recording in analog (Analog Recording) (page 25) to record using analog (line) input. Difference between digital (optical) and analog (line) inputs Difference Digital (optical) input Analog (line) input Equipment with an analog (line) output jack (Casette deck, radio, record player, etc.) Line cable (with 2 phono plugs or a stereo-mini plug) (page 25) Analog Even when a digital source (such as a CD) is connected, the signal sent to the recorder is analog. Connectable Equipment with a digital (optical) source output jack (CD player, DVD player, etc.) Usable cord Signal from the source Optical cable (with an optical or an optical-mini plug) (page 17) Digital

Use the connecting cords without an attenuator. To connect to a portable CD player with a stereo mini-jack, use the RK-G136 connecting cord. For more information on connecting cords, see (Optional accessories, page 64).
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 (stereo) recording time. Monaural recording at 2 times normal recording time is also possible. 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.

Recording tracks using the group function (Group Mode Recording)
What is the group function (Group Mode)? It is a function that allows you to separate tracks on a disc into different groups for playback, recording and editing.
When group mode is OFF. Disc Track number

LP: is added to tracks checked-out in LP stereo from your computer regardless of the LP Stamp setting. If you want to delete LP:, do the procedure Relabeling recordings (page 39)
Audio components that support the LP2 stereo or LP4 stereo modes are indicated by the or logo marks. If you set the recorder so that LP: is not added at the beginning of the track, you will be able to enter longer track names by using the full length of the text string Relabeling recordings (page 39). You can achieve high sound quality and rich tones when recording in SP stereo (or monaural) thanks to the newly developed DSP TYPE-R for ATRAC (Adaptive TRansform Acoustic Coding) (page 18).
When group mode is ON. Disc Group 1 Track number Group 2 Track number Group 3 Track number
It is recommended that you use the AC power adaptor 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 or earphones connected to the i jack. Sound recorded through digital (optical) input can be monitored in stereo through headphones/earphones, etc. 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 of 4 times longer than normal. If noise is produced, it is recommended that you record in normal stereo or LP2 mode to obtain better sound quality.
It is convenient for managing multiple CD albums recorded in MDLP (LP2 stereo/ LP4 stereo) mode onto a single MD. You can create a maximum of 99 groups on a disc.
How is group information recorded? When recording in group mode, the group information is written to the disc name recording area. This information consists of text strings that are written as shown in the following example.
Disc name recording area Example

END SEARCH

REC GROUP

./>/N

Disc name: Favorites Group name for tracks 1 to 5: Rock Group name for tracks 6 to 9: Pops
To activate group mode (Group Mode Recording)
To record tracks in group mode, you must first turn group mode on before the start of recording.
Therefore, the above character string is displayed in its entirety as the disc name if you load an MD recorded in group mode into a system that does not support group mode, or if you try to edit the contents of a disc on this recorder with group mode turned off. It is possible to change the character string by doing Relabeling recordings procedure in the Labeling/relabeling recordings (page 37). Note that if you rewrite this character string by mistake, you may be unable to use the group function of that MD.

To add a track that is playing to a group, stop playing the track first, and then do the procedure from step 3.
To start recording from the current point Select FrHere in step 4.
To temporarily record without recording over the current contents, press END SEARCH before the start of recording. The recording will begin after the last track, even if R-Posi is set to FrHere (factory setting). The remaining recordable time on the disc will appear in the display when you press END SEARCH.
The setting will remain even after the power is turned off. If you start recording while the recorder is in play-pause mode, the recording will begin from the point at which it is paused even when the R-Posi is set to Fr End.
To cancel Auto Time Stamp Select OFF, and then press ENTER in step 3, or stop recording. Using Auto Time Stamp to add track marks while recording
When the elapsed recording time exceeds the time interval for Auto Time Stamp:
Adding track marks automatically (Auto Time Stamp)
Use this feature to add track marks automatically at specified intervals when recording through the analog input connector.
The recorder adds track marks at the point you set the time interval and from that point the recorder adds a track mark whenever the time interval has elapsed. Example: Eight minutes of recording has been completed when the Auto Time Stamp time interval is set to 5 minutes. A track mark will be added at the 8minute 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:
While the recorder is recording or in recording pause, press MENU. Press. or > repeatedly until TimeMk flashes in the display, and then press ENTER. Press. or > repeatedly until the desired time interval flashes in the display, and then press ENTER. Select one of the following intervals: Time Approx. 5 min. Approx. 10 min. Approx. 15 min.
The recorder adds a track mark when the set Auto Time Stamp time interval has elapsed. Example: Three minutes of recording has been completed when the Auto Time Stamp time interval is set to 5 minutes. A track mark will be added at the 5minute point (after the start of recording) and after each 5-minute interval thereafter.
T appears before the track display on the recorder for track marks added by Auto Time Stamp.
Display OFF 5 min 10 min 15 min
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 is stopped.

Quick Random Access

Explanations

What is Net MD?

Net MD is a format of that allows the highspeed transfer of audio data from a computer to a MiniDisc device over a USB (Universal Serial Bus) cable using the highly sophisticated OpenMG and MagicGate copyright protection technology. Since this format entails no change in the MiniDisc recording system, it supports the use of existing MiniDiscs and the playback of transferred (checked-out) audio data on existing MiniDisc devices.* This format also allows the use of the OpenMG Jukebox software for easy editing or input of characters on your personal computer.
Audio data transferred in LP mode must be played on MiniDisc devices that support MDLP mode.
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.
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 extracts and encodes only those frequency components actually audible to the human ear.
A User TOC Area Contains the order and start/end points of the music. B Music Data

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)).
Restrictions on the editing of tracks checked out from your computer
This unit was designed so that editing functions (i.e., erasing tracks, adding track marks, and erasing track marks) do not function for tracks that have been checked out from your computer. This is to prevent the loss of check-in authorization by the checked-out tracks. To edit these tracks, first check them back into the computer, and then edit them on the computer.
