High Quality Content by WIKIPEDIA articles! CloneCD is proprietary optical disc authoring software that makes exact, 1:1 copies of music and data CDs and DVDs, regardless of any Digital Rights Management (DRM) restrictions. It was originally written by Oliver Kastl and offered by Swiss company Elaborate Bytes, but due to changes in European copyright law, they were forced to take it off the market. The software is now sold by SlySoft, a company located in Antigua and Barbuda, whose legislation does not ban the circumvention of DRM schemes. The last version of CloneCD made by Elaborate Bytes was v4.2.0.2.
