caption_attribution_description: English: This is a BD-R XL Writable disc. The capacity of a triple layer Blu-ray disc is 100GB of data.
context_page_description: Blu-ray Disc, often known simply as Blu-ray, is a digital optical disc data storage format designed to supersede the DVD format, capable of storing several hours of video in high-definition. The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, and Xbox One. The name "Blu-ray" refers to the blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.
  The plastic disc is 120 millimetres in diameter and 1.2 millimetres thick, the same size as DVDs and CDs. Conventional or pre-BD-XL Blu-ray Discs contain 25 GB per layer, with dual-layer discs being the industry standard for feature-length video discs. Triple-layer discs and quadruple-layer discs are available for BD-XL re-writer drives.
  High-definition video may be stored on Blu-ray Discs with up to 1920×1080 pixel resolution, at 24 progressive or 50/60 interlaced frames per second. DVD-Video discs were limited to a maximum resolution of 480i or 576i.
context_section_description: The BDXL format allows 100 GB and 128 GB write-once discs, and 100 GB rewritable discs for commercial applications. The BDXL specification was finalised in June 2010. BD-R 3.0 Format Specification (BDXL) defined a multi-layered disc recordable in BDAV format with the speed of 2× and 4×, capable of 100/128 GB and usage of UDF2.5/2.6. BD-RE 4.0 Format Specification (BDXL) defined a multi-layered disc rewritable in BDAV with the speed of 2× and 4×, capable of 100 GB and usage of UDF2.5 as file system. Although the 66 GB and 100 GB BD-ROM discs used for Ultra HD Blu-ray use the same linear density as BDXL, the two formats are not compatible with each other, therefore it is not possible to use a triple layer BDXL disc to burn an Ultra HD Blu-ray disc playable in an Ultra HD Blu-ray player.
