BURN-Proof (Buffer Under Run Error Proof) is a technology developed by Sanyo that allows compact disc ( CD ) recording to automatically stop in the event of an unplanned interruption and then to resume recording. BURN-Proof is a registered trademark of Sanyo.

When a CD is burned (recorded), the data must usually be written onto the CD without any interruption. If an interruption, such as the opening of a new application, does occur, a Buffer Under Run error occurs and the burn is unsuccessful. BURN-Proof technology located on firmware inside the CD-R or CD-RW drive monitors the recording process. If the drive detects a Buffer Under Run error, it suspends recording. When the problem is resolved, the CD-R or CD-RW drive restarts recording data from where it stopped.

BURN-Proof technology is used with CD drive speeds 12x and higher because Buffer Under Run errors occur more often with faster drives. Many CD recording application vendors provide BURN-Proof support with their software.
