Recording an MD right away!
Connect to a digital source using an optical cable to make digital recordings. Digital recording is possible even from digital equipment with different sampling rates, such as a DAT deck or a BS tuner, using the built-in sampling rates converter (see Note on digital recording (page 59)). To record from an analog source, see Recording with analog input (line cable required) (page 22). It is recommended to use the supplied AC power adaptor when recording.

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. 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 (recorded in stereo), 24 seconds long (recorded in LP2 mode or monaural mode), or 48 seconds long (recorded in LP4 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 mode or monaural), or 8 seconds (in LP4 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).

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/ earphones directly to i/LINE OUT on the main unit or to a remote control, use only headphones/earphones with stereo mini plugs.

stereo mini plugs

micro plug
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 on page 69), 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.

Self-Diagnosis Result Display Mode
This set uses the self-diagnostic function system in which if an error occurred during the recording or playing, the mechanism control block and the power supply control block in the microcomputer detect it and record its cause as history in the nonvolatile memory. By checking this history in the test mode, you can analyze a fault and determine its location. Total recording time is recorded as a guideline of how long the optical pickup has been used, and by comparing it with the total recording time at the time when an error occurred in the selfdiagnosis result display mode, you can determine when the error occurred. Clear both self-diagnosis history data and total recording time, if the optical pickup was replaced. Self-Diagnosis Result Display Mode Setting Method 1. Setting the test mode (see page 12). 2. In the display check mode, press the [JOG LEVER $L% R] (up) key or [DISPLAY] key on the remote commander activates the self-diagnosis result display mode where the LCD display as shown below.
