Playing MP3 files
What is MP3?
A method of compressing audio, MPEG Audio Layer 3
(MP3) allows audio to be reduced to up to one tenth its
original size when a compression rate of 128 kbps is
used, without overtly hurting audio quality.
When creating MP3 files to play
on this unit
≥ Disc formats: ISO9660 level 1 and level 2 (except for
extended formats)
≥ Files: MP3 files with the suffix “.mp3” or “.MP3”
≥ MP3 files may not be played in the order you recorded
them. Note the following if you want the files to play in
the order you record them.
≥ 1 Use software that records the files to the disc in file
name order.
≥ 2 Prefix folder and file names with 3-digit numbers in
the order you want to play them.
≥ 3 Give the files and folders names with 8 characters
or less, including the 3-digit prefix.
≥ 4 It is better not to create folders (albums) within fold-
ers (such as shown in example 2).
This unit plays MP3 files in the following order.
Numbers such as
1 show the order folders (albums) and
files (tracks) within them are played.
Example1: Recommended method when creating MP3
discs.
Example2: A disc not created in the recommended way.
≥ Play will be in the order shown in the below diagram,
irrespective of folder and track names, so the order of
play in this example will be A
# C # G # D, not
A # B # C # D. Folders and files in the same level will
be played in order according to their names.
≥ Folders that do not contain MP3 files ( “Falbum” in the
example) are skipped.
Example2 Example1
Limitations on MP3
≥ This unit cannot play files if they have a suffix other
than “.mp3” or “.MP3”.
≥ This unit cannot play files that have the suffix “.mp3”
or “.MP3” if they are not MP3 files.
≥ This unit is not compatible with ID3 tags.
≥ This unit is compatible with multi-session but if there
are a lot of sessions it takes more time for play to
start. Keep the number of sessions to a minimum to
avoid this.
≥ This unit cannot play files recorded using packet write.

Frequently asked questions
Q. Can I play a disc if it has both audio data and
MP3 data?
Yes, but only the data type used for the first track is
played.
Q. Is there a limit on the number of albums and tracks?
This unit can play a maximum of 999 albums and
999 tracks. The unit cannot play albums or tracks
beyond these limits.
Q. Why is sound interrupted between tracks?
The pick-up lens has to move to find the next track
so a few seconds of silence is normal.
Q. Can I use 700-MB data?
Yes, you can.

Anti-Skip System
This system deals with skipping in a variety
of ways:
≥ An anti-skip mechanism prevents skipping caused
when play speed changes due to swinging of the unit.
≥ A recovery system immediately returns the laser pick-
up to its original position if it is knocked off the track by
a strong shock.
≥ The anti-skip memory (maximum 45 seconds when
playing CD-DA and maximum 100 seconds when
playing 128 kbps MP3) fills in interruptions caused by
bumps and vibrations.
The anti-skip system works automatically while the
system is on and cannot be canceled.
S-XBS
Note !
The anti-skip memory compresses digital signals.
When bumps continue repeatedly
The elapsed playing time disappears and sound is inter-
rupted.
The letters such as F in the various illustrations refer to the descriptions in the “Location of Controls” section (see page 2).
