Blu-ray (Blu-ray Disc or BD) is a digital optical disc data storage format designed to supersede the DVD format. It was invented and developed in 2005 and released worldwide on June 20, 2006, capable of storing several hours of high-definition video (HDTV 720p and 1080p). 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, PlayStation 5, Xbox One, and Xbox Series X. The name 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, resulting in an increased capacity.
The polycarbonate disc is in diameter and thick, the same size as DVDs and CDs. Conventional (or "pre-BDXL") Blu-ray discs contain 25GB per layer, with dual-layer discs (50GB) being the industry standard for feature-length video discs. Triple-layer discs (100GB) and quadruple-layer discs (128GB) are available for BDXL re-writer drives.
