What is a MiniDisc?

The disc is stored in a cartridge. Y ou can handle it easily without worrying about dust, fingerprints, etc. However, dust entering the opening of the cartridge, dirt on the cartridge, warping, etc. may cause malfunctions. Please note the following.

■

To prevent recorded MiniDiscs from being erased accidentally

Slide the accidental erase prevention tab, located on the side of the MiniDisc, in the direction indicated by the arrow.

● The MiniDisc will then be protected against accidental erasure.

Recordable

To add a recording to such a MiniDisc, slide the accidental erase prevention tab back to its original position.

■

Helpful tip when attaching a label

When attaching a label to a MiniDisc cartridge, be sure to note the following. If the label is not attached properly, the MiniDisc may jam inside the unit and it may not be possible to remove it.

● If the label peels off or partially lifts away, replace it with a new one.

● Do not put a new label on top of an existing one.

● Attach the label only in the specified location.

■

Types of discs

There are two types of discs: playback-only and recordable types.

● Playback-only MiniDisc:

This type of MiniDisc is used for commercially available prerecorded music. This is the same kind of optical disc as CDs. Playback is performed using an optical pickup. (Recording and editing are not possible.)

● Recordable MiniDisc:

This is a “raw disc” on which recording can be performed. A magneto optical disc is used. Recordings are made using a laser and magnetic field. Repeated recording is possible.

Recording prevented

A Shutter will be used on only one side (back).

Shutters will be used on both sides.

MiniDisc System Limitations

Even if the maximum recording time of a MiniDisc has not been reached, “TOC FULL” may be displayed.

Even if the maximum recording time of a MiniDisc has not been reached, “DISC FULL” may be displayed.

Even if several short tracks are erased, the remaining recording time may not show an increase.

Two tracks may not be combined in editing.

The total of the recorded time and time remaining on a disc may not add up to the maximum possible recording time.

If recorded tracks are fast reversed or fast forwarded, the sound may skip.

In the MD system, the delimiter of the recording area on a MiniDisc is programmed in a TOC. If partial erasing, recording and editing are repeated several times, TOC information will fill up, even though the number of tracks has not reached the limit (255 tracks), and further recording will be impossible. (If you use the all erase function, this MiniDisc can be used from the beginning.)

If there is any flaw on the MiniDisc, that part is automatically excluded from the space available for recording. Therefore, the recording time becomes shorter.

When the remaining recording time of a disc is displayed, short tracks less than 12 seconds long may not be included in the total.

For MiniDiscs on which repeated recording and editing operations were performed, the COMBINE function may not work. A track recorded from a CD (digital recording) and a track recorded from a radio or other equipment (analogue recording) cannot be combined.

A cluster (about 2 seconds) is normally the minimum unit of recording. So, even if a track is less than 2 seconds long, it will use about 2 seconds of space on the disc. Therefore, the time actually available for recording may be less than the remaining time displayed. If there are scratches on discs, those sections will be automatically avoided (no recording will be placed in those sections). Therefore, the recording time will be reduced.

A MiniDisc which has been recorded or edited repeatedly may skip during fast reverse or fast forward.

Measure to be taken when a disc cannot be removed due to a mechanism trouble

First, remove the mechanism unit section from the set, and check for the state of the disc. (Remove the top plate R if necessary.) <State of the disc> (1) When the disc is in the normal PLAY (chucking) position -> Try to eject the disc by turning the mode big gear/tray big gear

manually. * At this time, be sure to adjust the tray's position (height). (2) When the disc is in the normal STOCK position -> Try to eject the disc by turning the tray big gear manually. * At this time, be sure to adjust the tray's position (height). (3) When the disc is not in the normal position -> The tray or disc is not in the normal position. (The tray or disc may catch

somewhere.)

Remove the TOP PLATE F/DISC OB lever. Unlock the tray lock lever and pull out the tray which is not caught. Move the caught tray or disc and remove the disc.

In case of (1) and (2), the mechanism is normal (defective circuit parts, etc.). However, it may stop somewhere. This is the reason why you should try to turn the tray big gear first. In case of (3), either of the big gears does not turn.
