About MP3 discs

What is MP3?

MP3 is an abbreviation of Motion Picture Experts Group (or MPEG) Audio Layer 3. MP3 is simply a file format with a data compression ratio of 1:10 (128 Kbps*). That means, by using MP3 format, one CD-R or CD-RW can contain 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 unit used is Kbps. To get a better audio quality, choose a higher bit rate. The most popular bit rate for encoding is 128 Kbps.

Incompatible with ID3-tag

ID3-tag is extra information data stored within an MP3 file such as album title, performer name, song title, recording year, music genre and a brief comment.

• This unit cannot show ID3-tag on the display.

How are MP3 files recorded?

MP3 files can be recorded in “folders.” During recording, the files and folders can be arranged in a way similar to arranging files and folders of computer data.

“Root” is similar to the root of a tree. Every file and folder can be linked to and be accessed from the root.

		Hierarchy
Level 1	Level 2	Level 3	Level 4	Level 5

01	02	03		6
ROOT	3		4	7
05	10		5
1	11	04		8
