You cannot pause manually during synchrorecording. When there is no sound from the player for more than 3 seconds during synchrorecording, 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.
Do not switch SYNCHRO REC after step 3. Recording may not be done properly. When recording in monaural, follow steps 1 to 3 of Recording in monaural for double the normal recording time (page 17), and then do steps 1 and 3 of synchro-recording. 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 connecting cord is not an optical cable, or if the cable is connected to the MIC (PLUG IN POWER) jack.

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 TR FULL appears even before the disc has reached the maximum recording time (60, 74, or 80 minutes). TR FULL 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. The total recorded time and the remaining time on the disc may not total the maximum recording time (60, 74, or 80 minutes). Cause 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.
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 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. Tracks of under 12 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. When recording is stopped, the last unit of recording always uses this unit of 2 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 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 compared to the potential recording time for each stop. The fragmentation of data may cause sound dropout while searching because the tracks are played in higher speed than normal playback.

The edited tracks may exhibit sound dropout during search operations.

What is an MD?

How MiniDisc works
MiniDisc (MD) comes in two types: premastered (prerecorded) and recordable (blank). Premastered MDs, recorded at music studios, can be played back almost endlessly. However, they cant be recorded on or over like cassette tapes. To record, you must use a recordable MD. Premastered MDs Premastered MDs are recorded and played like regular CDs. A laser beam focuses on the pits in the surface of the MD and reflects the information back to the lens in the recorder. The recorder then decodes the signals and plays them back as music.
Whether you should plug the headphones directly to i/LINE OUT on the main unit or to a remote control, use only headphones with stereo mini plugs.

stereo mini plugs

Recordable MDs Recordable MDs, which use magnetooptical (MO) technology, can be recorded again and again. The laser inside the recorder applies heat to the MD, demagnetizing the magnetic layer of the MD. The recorder then applies a magnetic field to the layer. This magnetic field corresponds exactly to the audio signals generated by the connected source. (The north and south polarities equate to digital 1 and 0.) The demagnetized MD adopts the polarity of the magnetic field, resulting in a recorded MD.
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.
