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 sec- ond, or bps units (bits per second). The higher the rate, the more infor- mation 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 record- ing 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.

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 edit- ed using software with ID3 Tag edit- ing functions. Although the tags are restricted to the number of charac- ters, 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 follow- ing 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 charac- ters (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).

MP3

MP3 is short for MPEG1 & 2 Audio Layer3. It is an audio compression standard set by a working group (MPEG) of the ISO (International Standards Organization). MP3 is able to compress audio data to about 1/10 the level of a conventional disc.

WMA

WMA is short for Windows MediaTM Audio and refers to an audio com- pression technology that is developed by Microsoft Corporation. WMA data can be encoded by using Windows Media Player version 7 or later.

Microsoft, Windows Media, and the Windows logo are trademarks, or registered trademarks of Microsoft Corporation in the United States and/ or other countries.
