Notes on MP3 discs
An MP3 file stores audio data compressed using MPEG1,
the audio layer-3 file-coding scheme.
In this manual, we refer to what, in PC terminology , are
called "folders" and "files" as "albums" and "tracks".
Notes on playing MP3s
• An MP3 track must be recorded on a disc in the format
compliant with ISO 9660. Note however , that the unit may
not play tracks in the order they were recorded.
• The maximum allowable number of tracks and/or albums
in a disc is 900, including the root albums (directory).
• The maximum allowable depth of a nested folder is 127,
including files.
• If a disc contains audio tracks and MP3 tracks, the unit
cannot play it.
• As for multi-session discs, the unit can play up to 20
sessions.
• The unit can play only MP3 tracks which were converted
with a sampling frequency of 44.1 kHz and a fixed bit
rate of 128 kbps.
• The unit may not play MP3 tracks recorded using a packet
writing utility .
• The unit can play only MP3 tracks having a file extension
".mp3".
• It may take 30 seconds or more before the unit can start
play of MP3 tracks, depending on the number of recorded
tracks and the complexity of the album tree.
• If you play a non-MP3 track that has the ".mp3" file
extension, it will skip to the next valid track automatically .
•Digital recordings with this unit cannot be done while
playing back MP3 discs.
Notes on display indications during playback
•Up to 8 characters are displayed for the name of an album
or track.
•Characters other than uppercase letters ("A" to "Z"),
numerals ("0" to "9") and underscore ("_") may not be
displayed, or may be displayed in dif ferent characters.
• The elapsed playing time may not be displayed correctly
for MP3 tracks.
• Depending on the condition of the recording equipment
or the CD-R/R W disc itself, a false album or track which
cannot be played on the unit may be displayed on TV
screen.
PLAYING BACK AN MP3 DISC
Notes on creating MP3 discs
•When converting audio data to MP3
Create MP3 files with a sampling frequency of 44.1 kHz
and a fixed bit rate of 128 kbps.
• When creating MP3 discs
Do not store more than 900 albums and/or tracks in a
disc.
•To play tracks in the order they were recorded
1.Use a writing software capable of recording MP3 tracks
(files) in numerical and alphabetical order . For details
on using the software, refer to the operating
instructions supplied with the software.
2.Use only one album. (Do not create a sub-album within
an album.)
3.Include a two or three-digit number at the beginning
of each album or track name so that the albums and
tracks are played in order .
<Example of recommended name structure>
01XXXXX.mp3
02XXXXX.mp3
03XXXXX.mp3
04XXXXX.mp3
05XXXXX.mp3
<Avoid using the following structure>
1XXXXX.mp3
5XXXXX.mp3
10XXXXX.mp3
15XXXXX.mp3
20XXXXX.mp3
(The beginning numbers determine the order , therefore
the tracks shown above will be played in wrong order ,
i.e., "1", "10", "15", "20", and "5".)
Glossary
File extension:
A 3-character string added to a file name under the
Windows or DOS environment is called a "file extension".
A file extension is used mainly to identify types of files. The
file extension for MP3 files is ".mp3".
ISO 9660:
ISO stands for the "International Organization for
Standardization". ISO 9660 determines the file structure
for the CD-ROMs. This unit can play MP3 files recorded in
the format compliant with ISO 9660.
Nesting of folders (albums):
To organize data files stored in a PC, you can store related
files in a folder . A folder can contain other folders as well
as files. For example, folder A can contain folder B, and
folder B can contain folder C; this is called "nesting of
folders".
Session:
A session is one uninterrupted section of written data on a
disc.
A multi-session disc is a disc which has more than two
sessions.
