The Blu-ray Disc Association on Friday finalized its proposed BDXL format for Blu-ray discs. The advance will allow up to 128GB of storage space on write-once and rewritable discs. BDXL will be aimed mostly at video producers and others who need to write a large amount of data to a removable backup, with triple-layer 100GB rewritable (RE) and write-once (R) discs as well as quadruple-layer 128GB R discs.
