USING DISCS

Before playing or recording on a disc, read this section thoroughly.

USABLE DISCS

This unit has two CD player systems.

One is a CD player located on top of the unit, on which a conventional music CD, a finalized* CD-R or a finalized CD-RW can be played.

The other is a CD-R/RW player/recorder located on the lower part of the unit, on which a conventional music CD, a CD-R or a CD- RW can be played and a CD-R or a CD-RW can be recorded on. * See "Finalization" in the right column.

TYPE OF DISCS

• CD-R and CD-RW discs

For recording and playback, you can use the CD-R and CD-RW discs with the following logos.

Be sure that the logos have "DIGITAL AUDIO" which indicates the CD-R or CD-RW is for audio use. It is not assured that operations such as playing and recording can be performed on this unit correctly if you use a CD-R or CD-RW without this mark.

Material recorded on a CD-R disc cannot be erased, while material recorded on a CD-RW can be erased, thus a CD-RW can be recorded repeatedly.

A finalized CD-R disc can be played on conventional CD players as well. A CD-RW disc can be played only on CD-RW players.

• Conventional music CDs

Discs with the following logo can be played on this unit, but no recordings can be made on them.

When you load a CD-R, CD-RW or any other disc that is not compatible with this unit, "Check Disc" or "No Audio" may appear on the display to warn you that the disc cannot be used in this unit for recording.

CAUTION

Do not open and close the CD-R/RW player/recorder tray unnecessarily with a non-finalized CD-R disc inside. For the reason why, see "OPC" in the right column.

WARNING

Digital recording capabilities this unit provides you with are only for personal use.

Dubbing copyrighted material without permission of the copyright owner is a violation of the copyright laws.

TERMS AND FEATURES

• Finalization

Finalization is the process of embedding a Table Of Contents (TOC) on a CD-R or CD-RW on which recording is completed. This process enables a CD-R and CD-RW to be played on the CD player of this unit or any other conventional CD players. (CD- RW discs, however, can be played only on CD-RW players.)

See "FINALIZATION" on page 23 for details.

• OPC (Optimum Power Control)

When a non-finalized CD-R or CD-RW is loaded on the CD-R/ RW player/recorder, OPC determines the intensity of the recording laser beam that is best for the currently loaded disc. OPC can run only a limited number of times (500 times) on a non-finalized CD-R. Therefore, do not open and close the CD- R/RW player/recorder tray unnecessarily when a CD-R is loaded. When a CD-R approaches its OPC limit, "OPC Full" is displayed. In such a case, see "FINALIZATION" on page 23 and finalize the disc.

OPC does not run on a finalized disc.

• SCMS (Serial Copy Management System)

When digital recording is attempted from recorded material with copyrights, digital dubbing cannot be performed to a CD-R or CD-RW from another disc recorded in digital because of the built-in record restriction function which complies with the SCMS standard.

SCMS is the standard to restrict single digital dubbing between digital audio systems thus protecting copyrights.
