WHAT IS A MINIDISC?

The disc is stored in a cartridge.You can handle it easily with- out worrying about dust, fingerprints, etc. However, dust en- tering the opening of the cartridge, dirt on the cartridge, warp- ing, etc. may cause malfunctions. Please note the following.

■Handling the MiniDisc

Do not touch the disc directly!

Do not open the shutter or touch the disc directly. If the shutter is opened forcibly, it may break.

■Adaptive TRansform Acoustic Coding [ATRAC]

The ATRAC (Adaptive TRansform Acoustic Coding) is a new technology that is designed to eliminate the information in sounds which you can not hear and to compress the remain- ing sound data so that the recording uses about 1/5 of the original sound information. Sound data is analyzed and filtered to take advantage of psycho acoustic masking. The acoustic quality of the sound is not impaired.

■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. (Re- cording and editing are not possible.)

Where not to store discs:

Do not store discs in places with high temperatures or hu- midity. Specifically, do not leave discs in places exposed to direct sunlight or in cars with doors and windows closed. Do not leave discs in places where sand can get into the car- tridge easily (e.g. beaches).

■To prevent recorded discs from being erased accidentally

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

●The disc will then be protected against accidental erasure.

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

■What is a MiniDisc?

●A MiniDisc is a 2-1/2" (64 mm) diameter disc which is stored in a cartridge. MiniDiscs are easy to handle, compared to CDs, because they are protected against dust and scratches.

●Recording and playback use a digital system with a sound quality that is similar to that found on CDs.

MiniDiscs cannot twist or stretch like tapes. The quality of sound will not deteriorate. MiniDiscs are extremely durable.

●Never disassemble MiniDiscs.

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

●Recordable MiniDisc:

This is a "raw disc" on which recording can be performed. A magneto optical disc is used. Recordings are made us- ing a laser and magnetic field. Repeated recording is pos- sible.

Shutters will be used on both sides.

■How to apply labels

When sticking a label on a MiniDisc cartridge, be sure to ob- serve the following. If a label is not affixed properly, a MiniDisc may become jammed in the unit such that it can not be removed.

●Stick a label correctly to the specified area.

(Do not stick labels to areas other than the specified one.)

●Do not stick one label upon another.

●If a label is peeling off or starts to come

loose, replace it with a new one.

■Shock Resistant Memory

During playback, approximately 10 seconds of information is stored in the semiconductor memory. Therefore, even when the pickup cannot read information for a second or two due to an external shock, the sound continues without interruption because the information stored in memory is output.
