TOC

Table of Contents, Directory of the CD. The table of contents documents not only the number of tracks but also their starting position and the total length of the data area of the disc.

Track

a track is a section of the CD. Every audio title has its own track. In contrast, all the data of a data CD is contained within a single track. A Mixed-Mode CD has a data track (track 1) and audio tracks. The data track cannot be played back with an audio player. Older devices can produce a whistling sound which can damage your stereo system. The data track for CDs conforming to the Blue Book standard (CD-Extra, CD-Plus) is located at the end of the CD.

Track-at-Once

"Track-at-Once"isamethodofwritingbywhichalltracksarewrittenindividually. For data CDs there is no significant difference to "Disc-at-Once"; however, a gap of two seconds is appended to every track of an audio CD.

Some CD recorders can only write according to this method.

Virtual Image

The data structure of a CD is different to those of other media. The writing program must first convert the data in to an appropriate form before it sends it to the recorder. The virtual image is constantly updated during the writing procedure. This requires a computer system with enough power to handle the complexity of the data. The virtual image requires approx. 30MB of free hard disk space. It is automatically deleted after the writing procedure. Writing with virtual images is also known as "On-the-Fly." If problems occur (insufficient data transfer rates), you should use physical images to separate the image creation and data transfer/writing processes.
