This is a general term that describes the
process of writing data on-demand to CD-
R, etc., in the same way that data is writ-
ten to floppy or hard discs.
 This is a method of embedding track-
related information in an MP3 file. This
embedded information can include the
track number, track title, the artist’s name,
the album title, the music genre, the year
of production, comments, cover art and
other data. The contents can be freely
edited using software with ID3 tag editing
functions. Although the tags are restricted
to a number of characters, the information
can be viewed when the track is played
back.
 WMA files can contain a WMA tag that is
used in the same way as an ID3 tag. WMA
tags carry information such as track title
and artist name.
 This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are 2 lev-
els of regulations.
 Level 1: The file name is in 8.3 format (8
character file names, with a 3 character
file extension. File names must be com-
posed of one-byte capital letters and num-
bers. The “_” symbol may also be
included.)
 Level 2: The file name can have up to 31
characters (including the separation mark
“.” and file extension). Each folder must
contain fewer than 8 hierarchies. 
MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on conventional
discs.
 WMA (Windows Media Audio) is an audio
compression format developed by
Microsoft
®. It compresses files into a size
smaller than that of MP3 files. The decod-
ing formats for WMA files are Ver. 7, 8 and
9. This product is protected by certain
intellectual property rights of Microsoft
Corporation and third parties. Use or dis-
tribution of such technology outside of this
product is prohibited without a license
from Microsoft or an authorized Microsoft
subsidiary and third parties.
 AAC is short for Advanced Audio Coding
and refers to an audio compression tech-
nology standard used with MPEG2 and
MPEG4.

MP3 AND WMA FILES
MP3 (MPEG Audio LAYER3) is a stan-
dard audio compression format. Files
can be compressed to approximately
1/10 of their original size by using MP3
compression.
WMA (Windows Media Audio) is a Mi-
crosoft audio compression format. This
format compresses audio data to a
size smaller than that of the MP3 for-
mat.
There is a limit to the MP3 and WMA
file standards and to the media/formats
recorded by them that can be used.
