cdrtools (formerly known as cdrecord) is a collection of independent projects of free software/open source computer programs. It has been adapted to use on Windows. The collection includes many features, such as :

• support for creation of audio, data, and mixed (audio and data) CDs.
• support for burning CD-R, CD-RW and DVD-R, DVD-RW, DVD+R and DVD+RW, both single and dual layer DVDs.
• support for several different burning modes, such as Track-At-Once and Disc-At-Once
• support for cue sheet based writing using the control file format from cdrwin
• nearly complete support for Blu-ray Discs
• support for many vendor specific drive features is implemented.

The project collection called cdrtools was created by Jörg Schilling and others under the GNU General Public License (GPL). The sub-project mkisofs completely remains under GPL. The most important parts of the package are cdrecord, a console-based burning program; cdda2wav, a CD audio ripper that includes libparanoia support; and mkisofs, a CD filesystem image creator. Because these tools don't include any GUI, many graphical front-ends have been created (see Software that can use cdrtools section).

Licensing change

In recent versions, starting with 2.01.01a09, most code from cdrtools has been relicensed under the CDDL, while other parts are still licensed under the GPL. In the opinion of most observers, this change makes it impossible to legally distribute cdrtools binaries.

Debian, Red Hat, SUSE and Mandriva dropped the versions of cdrtools with CDDL code from their distributions. The Debian project created cdrkit, a fork of cdrtools. In August 2008, Mark Shuttleworth offered to ask the Software Freedom Law Center for a legal opinion on whether cdrtools could be included in Ubuntu, provided Schilling agreed to accept the opinion.<ref>"Minutes from the Technical Board meeting, 2008-08-26".

Since the licensing change, cdrtools added some bug fixes and new features, such as UTF-8 support for mkisofs, support for multi extent files (> 4 GB) in mkisofs, support for correct hard links in mkisofs and Blu-ray support in cdrecord.
