About the 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. This unit supports the TYPE-R function only during recording or playback in normal stereo mode. It does not support this function in MDLP mode, or during the checking out of audio data from the computer in normal stereo mode using OpenMG Jukebox.
The pause function cannot be turned on or off manually during synchro-recording. Flip the control bar towards x to stop recording. Do not switch the SYNC REC 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. 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 change the recording mode during recording. Data Save or TOC Edit flashes while data of the recording (the tracks start and end points, etc.) is being recorded. Do not move or jog the recorder or disconnect the power source while the indication is flashing in the display. The lid does not open until TOC 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 TOC Edit appears in the display, then it will not be possible to open the lid until power is restored. You can make 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.

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.

If you have any questions or problems concerning your recorder, please consult your nearest Sony dealer. (If a trouble occurred when the disc was in the recorder, we recommend that the disc be left in the recorder when you consult your Sony dealer so that the cause of trouble may be better understood.)

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) and the recording cannot be done. TR FULL appears even before the disc has reached the maximum track number or recording time. 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 SP stereo), 24 seconds long (recorded in LP2 stereo mode or monaural mode), or 48 seconds long (recorded in LP4 stereo 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 SP stereo), 4 seconds (in LP2 stereo mode or monaural), or 8 seconds (in LP4 stereo 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.

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).
The edited tracks may The fragmentation of data may cause sound dropout while exhibit sound dropout during searching because the tracks are played in higher speed search operations. than normal playback.

Symptom

A track cannot be recorded Group information has been written to the area where the to a new group. A new group disc name is stored. The disc name and track names are recorded in the same area, which can store a maximum of cannot be created. approximately 1,700 characters. If the total number exceeds this amount, a new group cannot be created even though group mode is on. It is also impossible to make group settings at this time. The playing time of a checked-out track is different from the time that appears on your computer monitor. You cannot check out tracks that will fill up the remaining recording time on the disc. (For example, you cannot check-out tracks that total 160 minutes to an 80minute disc in LP2 stereo mode.) This is due to a calculation discrepancy between the recorder and the computer.
The minimum recordable time on a disc is normally 2 seconds in stereo, 4 seconds in LP2 stereo mode, and 8 seconds in LP4 stereo mode. When you check out a track from your computer, the recorder needs a 2-second (or 4or 8-second) space for a track even if the track is under 2 seconds (or 4 or 8 seconds) in length. Also, the recorder inserts a 2-second (or 4 -or 8-second) space in between tracks during check out so as not to overwrite the previous track by mistake. For this reason, the recorder needs an additional 6 seconds (or 12 or 24 seconds) for each track. This reduces the maximum recording time for each track by 6 seconds (or 12 or 24 seconds) during check out. To erase a track that has been checked out from your computer, check it back in first, and then erase it using the OpenMG Jukebox software. The recorder turns off 3 minutes after the recorder has stopped in order to allow the charging time on the USB cradle to be calculated.
You cannot erase a track checked out from your computer. When using with the AC power adaptor, the display window of the recorder will remain faintly lit for some time even after the recorder 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, 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.

Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
