Disc Play Introduction, When playing a CD-R or CD-RW

Disc Play Introduction

This unit has been designed to play back the following discs:

•CD (Audio CD)/CD-R (CD-Recordable)/CD-RW (CD- ReWritable)

•MP3 disc (MP3 files recorded on a CD-R or CD-RW)*

When playing a CD-R or CD-RW

User-edited CD-Rs (CD-Recordable) and CD-RWs (CD-ReWritable) can be played back only if they have been “finalized.”

•You can play back your original CD-Rs or CD-RWs recorded in music CD format or in MP3 format. However, they may not be played back depending on their characteristics or recording conditions.

•Before playing back CD-Rs or CD-RWs, read their instructions or cautions carefully.

•Some CD-Rs or CD-RWs may not play back on this unit because of their disc characteristics, damage or stain on them, or if the player’s lens is dirty.

•CD-RWs may require a longer readout time. This is caused by the fact that the reflectance of CD-RWs is lower than for regular discs.

*About MP3

MP3 is an abbreviation of Motion Picture Experts Group 1 (or MPEG-1) Audio Layer 3. MP3 is simply a file format with a data compression ratio of 1:10 (128 kbps*). By using MP3 format, one CD-R or CD-RW can contains 10 times as much data volume as a regular CD can.

*Bit rate is the average number of bits that one second of audio data will consume. The basic unit of measurement for bitrate is kbps (1,024 bits per second). To get a better audio quality, choose a higher bit rate. The most popular bit rate for encoding (recording) is 128 kbps.

MP3 disc structure

On an MP3 disc, each song (material) is recorded as a file. Files are grouped into a folder. Folders can also include other folders, creating hierarchical directory layers. (See “How are MP3 files recorded and played back?” on page 14.)

This unit manages files and folders as “tracks” and “groups.” This unit can recognize up to 255 groups per disc (up to 999 tracks). The unit ignores those exceeding the maximum numbers and cannot play them back.

About the CD ready lamps

Each CD ready lamp shows the status of a disc placed on each corresponding disc tray (CD1 – CD5).

CD1 READY

CD2 READY

CD3 READY

CD4 READY

CD5 READY

•CD ready lamps light up

When the disc is loaded and currently selected.

•CD ready lamps light slightly

When the disc is loaded, but not currently selected.

•CD ready lamp flashes

When the disc is played back or paused.

•CD ready lamps goes off

When the unit detects there is no disc loaded on a certain tray. (“NO DISC # (number)” appears on the display.)

If the loaded disc is an MP3 disc

The corresponding CD ready lamp and the MP3 indicator will light up.

More about MP3 discs

•MP3 discs (either CD-R or CD-RW) require a longer readout time. (It varies due to the complexity of the recording configuration.)

•When making an MP3 disc, select ISO 9660 Level 1 or Level 2 as the disc format.

•This unit does not support multisession recording.

•This unit can play MP3 files only with the following file extensions— “.MP3,” “.Mp3,” “.mP3,” and “.mp3.”

•Files other than MP3 are ignored.

•Some MP3 discs may not be played back because of their disc characteristics or recording conditions.
