If the recording does not start
Make sure the recorder is not locked (page 25). Make sure the MD is not record-protected (page 32). Premastered MDs cannot be recorded over.
For models supplied with the AC plug adaptor
If the AC power adaptor does not fit the wall outlet, use the AC plug adaptor.
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 unless powered by the AC power. Connect the AC power adaptor to the portable CD player and use it on AC power as the power source. Disable any anti-skip function (such as ESP*) on the portable CD player.
Electronic Shock Protection
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 level of the recorded sound is adjusted automatically. You can monitor the sound during recording. Connect the supplied headphones/earphones to i and adjust the volume by pressing VOL +/. This does not affect the recording level.

You cannot change the recording mode while recording. It is recommended that you use the AC power adaptor for long recordings. If you try to play an MD recorded in LP2 stereo or LP4 stereo on a player/recorder that is 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 stereo 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 stereo mode to obtain better sound quality.

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)

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.
A User TOC area Contains the order and start/end points of the music. B Music Data

MZ-R501/R501PC SECTION 1 SERVICING NOTE
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-4R) The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care. In performing the repair with the power supplied to the set, removing the MAIN board causes the set to be disabled. In such a case, fix a convex part of the open/close detect switch (S806 on MAIN board) with a tape in advance. Handle the FLEXIBLE board (overwrite head) with care, as it has been soldered directly to the MAIN board. In repairing the component side of MAIN board, connect the FLEXIBLE board (overwrite head) and the MAIN board with the lead wires in advance. (See page 7)
