Optical disc authoring and modify files, without having to write the whole disc again. A compatibility technology called HighMAT allows visual material on the disc to be recognised, interpreted and supported by electronic play devices more efficiently. Optical disc authoring Optical disc authoring, including DVD and Blu-ray Disc authoring is the process of assembling source material—video, audio or other data—into the proper logical volume format to then be recorded ("burned") onto an optical disc (typically a compact disc or DVD). To burn an optical disc, one usually first creates an optical disc image with a full file system, of a type designed for
Optical disc authoring require writing the entire disc at once, but allow writing of different parts at different times. This allows a user to construct a disc incrementally, as it could be on a rewritable medium like a floppy disk or rewritable CD. However, if the disc is non-rewritable, a given bit can be written only once. Due to this limitation, a non-rewritable disc whose burn failed for any reason cannot be repaired. (Such a disc is colloquially termed a "coaster", a reference to a beverage coaster.) There are many optical disc authoring technologies for optimizing the authoring process and preventing errors. Some
