zThis is a general term that describes the
process of writing da ta on-demand to CD-
R, etc., in the same way that data is written
to floppy or hard discs.
z This is a method of embedding track-
related information in an MP3 file. This
embedded information can include the
track title, the artist’s name, the album title,
the music genre, the year of production,
comments 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 charac-
ters, the information can be viewed when
the track is played back.
z 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. z
This is the international standard for the for-
matting of CD-ROM folders and files. For
the ISO 9660 format, there are 2 levels of
regulations.
z Level 1: The file name is in 8.3 format (8
character file names, with a 3 character file
extension. File names must be composed of
one-byte capital letters and numbers. The
“_” symbol may also be included.)
z 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.
z Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
z 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.
z 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.
