Terms
Packet write
This is a general term for a method
of writing on CD-R, etc. at the time
required for a file, just as is done
with files on floppy or hard discs.
Bit rate
This expresses data volume per
second, or bps (bits per second)
units. The higher the rate, the more
information is available to reproduce
the sound. Using the same encoding
method (such as MP3), the higher
the rate, the better the sound.
Multi-session
Multi-session is a recording method
that allows additional data to be
recorded later. When recording
data on a CD-ROM, CD-R or CD-
RW, etc., all data from beginning
to end is treated as a single unit or
session. Multi-session is a method
of recording more than 2 sessions in
one disc.
CD-DA
CD-DA is an abbreviation of
Compact Disc Digital Audio. It refers
to the uncompressed format of
regular CDs.

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.

format logic of CD-ROM folders and
files. For the ISO9660 format, there are
