What Does Burn Mean?
Burning is the process of recording to optical disc media, including writable CDs, DVDs and Blu-ray discs. The term is most associated with consumers creating CDs and DVDs and almost never applied to discs created by professionals for mass distribution. Professional creation of discs is referred to as “authoring” or “mastering” instead.
