About folders and files
lThe order of hierarchy for MP3 files
and folders during playback or other
functions is from shallow to deep. The
arrangement and playing order of a
recorded disc containing MP3 files is
as follows:
lFile number
A numerical file number is assigned
to each file in a folder in the order of
hierarchy from shallow to deep.
lFolder number
A numerical folder number is
assigned to each folder in the order
of hierarchy from shallow to deep.

02
04
03
15 4 2 3
Level1Level2Level3Level4
Folder
No.
lThe folder order is automatically
assigned and this order cannot be
optionally set.
lAny folder without an MP3 file will be
ignored. (It will be skipped and the
folder number will not be displayed.)
lMP3 files not conforming to the MP3
format containing both header frames
and data frames will be skipped and
not played.
lThis unit will play MP3 files that have
up to eight levels. However, the more
levels a disc has, the longer it will take
to initially start playing. It is
recommended to record discs with two
levels or less.
lA single disc with up to 999 files can
be played and a single folder with up to
255 files can be played.
lWhen naming an MP3 file, be sure to
add an MP3 file extension (.mp3) after
the file name.
lThe maximum number of characters
that can be used for file names is as
follows. However, this unit will only
display up to 30 characters, including
the file extension (.mp3).

CAUTION
This unit can only play MP3 files that
have an MP3 file extension (.mp3)
attached. Do not attach an MP3 file
extension to any other type file as it
could cause noise to be emitted or a
malfunction in the unit.
About ID3 Tag display
lThis unit can only display ID3 Tag
album, track and artist names that have
been input using Ver1.0/1.1/2.2/2.3
formats. Any other data that may have
been input cannot be displayed.
lThis unit can only display English
(including numerals) one-byte
characters. Use only English (including
numerals) one-byte characters when
inputting ID3 tags. Two-byte characters
and some special symbols cannot be
displayed.
Specialized glossary
MP3
Abbreviation for“MPEG Audio Layer 3”.
A technical standard for audio
compression as decided by an ISO
(International Organization for
Standardization) MPEG working group.
Use of MP3 allows for audio data to be
compressed to approximately a tenth of
the source data size.
ISO 9660
An international standard for logical
formatting of CD-ROM files and folders.
It is divided into three separate levels
based on differences in file naming
procedures, data configuration and other
characteristics.Multi-session
A session is the complete amount of data
recorded from the beginning to the end of
a single period of CD-ROM, CD-R/CD-
RW data recording. Multi-session refers to
the existence of data from two or more
sessions on a single disc.
Sampling
Refers to the process of encoding analog
audio data at regular intervals and
converting it to digital data. The sampling
rate refers to the number of times a
sample is taken in one second and is
expressed in Hz units. Increasing the
sampling rate improves the sound quality
but also increases the data size.
Bit rate
Refers to the volume of data per second,
expressed in bps (bits per second).
Generally, the larger the number of the
transfer bit rate when compressing an
MP3 file, the more information regarding
musical reproduction it carries, and
therefore the better the sound quality.
Packet writing
A general term for the method, similar to
that used for floppy discs or hard drives,
of recording the required file in a single
increment on a CD-R and similar.
ID3 Tag
ID3 tag is a method for storing
information related to the music in an
MP3 file. Information such as track, artist
and album name can be stored. This
content can be freely edited using ID3
editing function software.

VBR
Abbreviation for Variable Bit Rate. While
CBR (Constant Bit Rate) is generally
used, VBR varies the bit rate for audio
compression according to compression
conditions and this allows for
compression with preference given to
sound quality.
