CD−R/CD−RW discs that have not
been subject to the “finalizing process”
(a process that allows discs to be
played on a conventional CD player)
cannot be played.
It may not be possible to play CD−
R/CD−RW discs recorded on a music
CD recorder or a personal computer
because of disc characteristics,
scratches or dirt on the disc, or dirt,
condensation, etc. on the lens of the
unit.

the environment. Record with the cor-

appropriate application manufacturers
of the applications.)

by direct exposure to sunlight, high
temperatures or other storage condi-

some damaged discs.
If you insert a CD−RW disc into the

more slowly than with a conventional

TERMS
Packet write—
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
written to floppy or hard discs.
ID3 Tag—
This is a method of embedding track−re-
lated information in an MP3 file. This em-
bedded information can include the track
title, the artist’s name, the album title, the
music genre, the year of production, com-
ments and other data. The contents can
be freely edited using software with ID3 tag
editing functions. Although the tags are re-
stricted to the number of characters, the in-
formation can be viewed when the track is
played back.
WMA Tag—
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,
artist name.
ISO 9660 format—
This is the international standard for the
formatting of CD−ROM folders and files.
For the ISO 9660 format, there are two lev-
els of regulations.
Level 1:
The file name is in 8.3 format (8 character
file names, with a 3 character file exten-
sion. File names must be composed of
one−byte capital letters and numbers. 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 few-
er than 8 hierarchies.m3u—
Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
MP3—
MP3 is an audio compression standard de-
termined 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—
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
decoding formats for WMA files are Ver. 7,
8, and 9.
