Track
A disc is sub-divided into individual tracks - for example, separate songs or pieces
of music on an audio disc are each a track.
Track-At-Once (TAO)
With this method, each track is individually written onto the disc. The write
operation is briefly interrupted after each track. This means that a CD-R or CD-RW
can be written onto just like any standard disk.
Twin VQF File
The acronym for Twin Vector Quantization File, it is a format that is similar to the
MP3 format. It distinguishes itself by an even higher compression rate. Generally,
the files have approximately 30% less data than MP3 files however, with the same
quality.
UDF/ISO CD
The UDF file system has been especially optimized to handle large data quantities
and to also be able easily modify an existing file system just like you would on a
floppy however with a CD. This file format uses separate software and also formats
your disc differently.
Video CD
An acronym for “Video Compact Disc”, it holds movies and audio/video in stereo
with a compression standard called MPEG. One can also say that it is also based
on an ISO file system and contain digital video films. A video disc can be played on
most CD-ROM’s, DVD players, and DVD-ROM drives with the help of software.
Volume Descriptor
The Volume Descriptor is the area at the beginning of a CD in which the structure
of the file system is contained. It may also contain additional and optional
information about the CD, such as the name of the CD, the publisher, a copyright
notice, etc.
WAV/Wave File (with the extension .wav on your computer)
Audio files are saved on the hard disk in the wave format. The wave format is part
of the general RIFF Standard (Resource Interchange File Format). This format
supports various scanning rates and depths. This is the PC format for saving audio
files on the hard drive (Mac's use AIFF files). Audio files that are on a commercial
CD (store bought CD), are in digital form. When saving your sound/audio that
originates from a CD-ROM onto your hard drive, it must be saved in analog form.
Audio files cannot be saved in digital form on the hard drive.
White Book
The format created by Sony, Philips, and JVC in 1993 that extended the Red Book
CD format to include digital video in MPEG-1 format which is referred to as Video
CD.
