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.
