To write a write-once optical medium such as a CD-R, DVD-R or BD-R disc. Such a disc is considered "burned," because once recorded, it cannot be erased and rewritten. The term is also erroneously used for rewritable disks, such as CD-RWs and DVD-RWs, but rewritable media are not "burned;" they are "written." Burn means "once and done." See CD-R
