Editing Optical disc authoring (section)

==Software==
Use of optical disc recorders require ''optical disc authoring software'', sometimes called "burning applications" or "burner applications". Such software is usually sold with the recorder. Some [[operating systems]] come bundled with them.

Creating an optical disc usually involves first creating an [[optical disc image]] with a full [[file system]] designed for the optical disc, and then actually burning the image to the disc. Many programs create the disc image and burn in one bundled application (Quick Copy or Copy On-the-fly), such that end-users do not even know the distinction.

Disc file systems include [[ISO 9660]] (often known simply as “ISO”) and [[Universal Disk Format]] (UDF). ISO is most common for CDs and UDF is most common for DVDs.

There are also [[packet writing]] applications that do not require writing the entire disc at once, but allow writing parts at a time, allowing the disc to be used as a random access removable medium (somewhat like a very large floppy, though with unique constraints).

Sometimes, disc images are made to make the authoring process more straightforward. Sometimes disc images are even used to emulate the presence of a CD-ROM or DVD drive with the data entirely resident on the hard disc.

For the [[command-line interface|command-line]] tool ''[[cdrdao]]'', a so-called ''[[Table of Contents (CD)|TOC]] file'' that can be authored inside a [[text editor]] is used to specify the details of the desired disc record.<ref>{{cite web |title=cdrdao(1) - Linux man page |url=https://linux.die.net/man/1/cdrdao |website=linux.die.net |access-date=27 August 2020}}</ref>
