Thermal Recalibration
As your hard drive platters rotate, they expand due to the heat that is generated.
The hard drive will stop for a split second to readjust the heads (which does the
reading of data) to the newly expanded platter(s).
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.
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.
