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.
Recording with analog input (line cable required)
The sound will be sent from the connected equipment as analog signal but will be recorded digitally on the disc.
CD player, cassette recorder, etc. (source)

*Use the connecting cords without an attenuator. To connect to a portable CD player having a stereo mini-jack, use the RK-G136 connecting cord. For more information on connecting cords, see “Optional accessories” (page 68).
1 Insert a recordable MD, and then press and slide REC to the right. "REC" and the REC indicator light up in the display and the recording starts.
2 Play the source you want to record. For other recording operations, see "Recording an MD right away!" (page 16).

LINE IN (OPT) jack is for both digital and analog input.
The recorder automatically recognizes the type of line cable and switches to digital or analog input.
Note
If you temporarily stop a recording operation by pressing Ⅱ, a track mark will be added at that point when you press Ⅲ again to resume recording. The recording continues from on 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.

1 Press REC MODE repeatedly to select the desired recording mode.
| Recording mode1) | Display Recording time3) |
| Stereo (none) | approx. 80 min. |
| LP2 stereo LP | 2 approx. 160 min. |
| LP4 stereo LP | 4 approx. 320 min. |
| Monaural2) | MONO approx. 160 min. |
1) For better sound quality, record in normal stereo or LP2 mode. 2) If you record a stereo source in monaural, the sounds from left and right will be mixed. 3) When using an 80-minute recordable MD
2 Press and slide REC to the right.
3 Play the source you want to record.
To stop recording, press ■.
The recorder switches back to stereo recording when you record the next time.

Audio components that support the LP2 or LP4 modes are indicated by the MDLP MDLP logo marks.
Notes
- It is recommended that you use the supplied AC power adaptor for long recordings.
- If you try to play an MD recorded in LP2 or LP4 on a player/recorder that does 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 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 mode to obtain better sound quality.
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.
![graph TD A["CD players, etc."] --> B["Device with two USB connectors"] B --> C["Rec"] C --> D["OFF_ON SYNCHRO REC"]](/content/2026/06/1349959/images/0b00642885ace7ba7e99b892aa083573e7a38953299ba702cebee9ade3ff3254.jpg)

- You cannot pause manually during synchro-recording.
- When there is no sound from the player for about 3 seconds during synchro-recording, the recorder goes into the standby mode automatically. When the sound comes from the player again, the recorder resumes synchro-recording. If the recorder is kept in the standby mode for 5 minutes or longer, the recorder stops automatically.
- For longer recording; follow step 1 of "Recording for long times" (page 23) to select the recording mode, and then start the procedure of synchro-recording.
Notes
- Do not switch SYNCHRO REC 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 synchro-recording 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.
- Synchro-recording cannot be done if the connecting cord is not an optical cable, or if the cable is connected to the MIC (PLUG IN POWER) jack.
- You cannot manually change the recording level or the recording mode during synchro-recording.

4 Press the jog lever (L).
To cancel Auto Time Stamp
Select "OFF" in step 3 or stop recording.
Using Auto Time Stamp to add track marks while recording
After you set the time interval in step 4, the recorder will begin adding a track mark whenever the time interval has elapsed. For example, if an Auto Time Stamp interval of 5 minutes is set, and 8 minutes of recording has already been done, then a track mark will be added at a point equivalent to 13 minutes (8 + 5) after the start of recording, and every 5 minutes thereafter.
If, however, the Auto Time Stamp interval is longer than the elapsed recording time, then a track mark will be added when the Auto Time Stamp interval has elapsed. For example, if the Auto Time Stamp interval is set at 5 minutes, but only 3 minutes of recording has been done, then a track mark will be added at the 5-minute point after the start of the recording, and every 5 minutes thereafter.

"T" appears after the track number on the recorder for track marks added by Auto Time Stamp, and "T" appears after the time display on the remote control.
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 III, etc.).
- The setting will be lost when the recording is stopped.
