TERMS
Packet write—
This is a general term that describes the pro-
cess of writing data on−demand to CD−R,
etc., in the same way that data is written to
floppy or hard discs.
ID3 Tag—
This is a method of embedding track−related
information in an MP3 file. This embedded in-
formation can include the track title, the art-
ist’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. Al-
though the tags are restricted to the number
of characters, the information can be viewed
when the track is played back.
WMA Tag—
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, artist
name.ISO 9660 format—
