Optical disc authoring software is computer software for authoring optical discs including CD-ROMs and DVDs. They are also known by synonyms such as CD burning application or DVD authoring software. Such software is required to use an optical disc recorder.
Creating an optical disc usually involves first creating a disk image with a full file system designed for the optical disc, and then actually burning the image to the disc. Disk 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. Many programs create the disk image and burn in one bundled application, such that end-users do not even know the distinction.
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 like a floppy.
The standard open source optical disc authoring software is cdrtools, and is distributed with all Linux distributions. Many third-party commercial authoring software exist for Microsoft Windows; optical disc recorders are usually sold with bundled software.
