It is designed mainly for storing High-definition video, video games, and other data. Blue-ray Disc is from blue-violet laser that is used to read the disc. Blue-ray Disc has huge storage capacity of 25 GB (single layer disc) and 50 GB (double layer disc).
Standard DVD uses 650 nanometer red laser, whereas Blue-ray uses 405 nanometer blue-violet laser providing a storage capacity of six times more than a standard DVD with the same size as that of standard DVD. Blue-ray Disc was developed by the Blue-ray Disc Association, makers of computer hardware, motion pictures and consumer electronics.
Mini Blue-ray Disc is a compact one and stores approximately 7.5 GB of data. This is specifically designed for camcorders (portable video camera) and compact recording devices. BD-R (recordable) and BD-RE (rewritable) versions of Blue-ray Disc are developed for recording and rewriting purposes. Definitely Blue-ray Disc will dominate the next generation.
