Additional Information Terms ATRAC3 Short for "Adaptive Transform Acoustic Coding3". This is an audio compression technology for high-quality and high compression. It is possible to compress music data to about 1/10th the level of a CD, allowing miniaturization of storage media. Bit rate This expresses data volume per second, or bps units (bits per second). The higher the rate, the more information is available to reproduce the sound. Using the same encoding method (such as ATRAC3), the higher the rate, the better the sound. (As different encoding methods are use for MP3 and ATRAC3, a simple comparison is impossible.) ID3 Tag This is a method of embedding track-related information in a 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 the number of characters, the information can be viewed when the track is played back. ISO9660 format This is the international standard for the format logic of CD-ROM folders and files. For the ISO9660 format, there are regulations for the following two levels. Level 1: The file name is in 8.3 format (the name consists of up to 8 characters, half-byte English capital letters and half-byte numerals and the "_" sign, with a file-extension of three characters.) Level 2: The file name can have up to 31 characters (including the separation mark "." and a file extension). Each folder contains less than 8 hierarchies. Extended formats Joliet: File names can have up to 64 characters. Romeo: File names can have up to 128 characters. m3u Playlists created using the "WINAMP" software have a playlist file extension (.m3u). MagicGate Data recorded on a "MagicGate Memory Stick (MG Memory Stick)" is encrypted using copyright protection technology and can be mutually authenticated with "MG Memory Stick" compatible equipment. A "MG Memory Stick" can only be used to record and playback when there is verification between the "MG Memory Stick" and the compatible equipment. "MagicGate Memory Stick" This is the name used for a "Memory Stick" that uses the "MagicGate" copyright protection technology. This is an IC recording media for recording and playback of music and other data requiring copyright protection technology. 79

ATRAC3
Short for “Adaptive Transform Acoustic
Coding3”. This is an audio compression tech-
nology for high-quality and high compression. It
is possible to compress music data to about
1/10th the level of a CD, allowing miniaturiza-
tion of storage media.
Bit rate
This expresses data volume per second, or bps
units (bits per second). The higher the rate, the
more information is available to reproduce the
sound. Using the same encoding method (such
as ATRAC3), the higher the rate, the better the
sound. (As different encoding methods are use
for MP3 and ATRAC3, a simple comparison is
impossible.)
ID3 Tag
This is a method of embedding track-related
information in a MP3 file. This embedded infor-
mation 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 the number of characters,
the information can be viewed when the track is
played back.
ISO9660 format
This is the international standard for the format
logic of CD-ROM folders and files. For the
ISO9660 format, there are regulations for the
following two levels.
Level 1:
The file name is in 8.3 format (the name con-
sists of up to 8 characters, half-byte English
capital letters and half-byte numerals and the
“_” sign, with a file-extension of three charac-
ters.)
Level 2:
The file name can have up to 31 characters
(including the separation mark “.” and a file
extension). Each folder contains less than 8
hierarchies.
Extended formats
Joliet:
File names can have up to 64 characters.
Romeo:
File names can have up to 128 characters.
m3u
Playlists created using the “WINAMP” software
have a playlist file extension (.m3u).
MagicGate
Data recorded on a “MagicGate Memory Stick
(MG Memory Stick)” is encrypted using copy-
right protection technology and can be mutually
authenticated with “MG Memory Stick” compati-
ble equipment. A “MG Memory Stick” can only
be used to record and playback when there is
verification between the “MG Memory Stick”
and the compatible equipment.
“MagicGate Memory Stick”
This is the name used for a “Memory Stick” that
uses the “MagicGate” copyright protection tech-
nology. This is an IC recording media for
recording and playback of music and other data
requiring copyright protection technology.
