IntroductionIntroduction• A current, single-sided, standard DVD can hold 4.7 GB
(gigabytes) of Information. That's about the size of an average two-hour, standard-definition movie with a few extra features
• Blu-ray is the next-generation digital video disc. It can record, store and play back high definition video and digital audio, as
well as computer data.
Working of Blu-RayWorking of Blu-Ray
• Blu-ray has reduced the track pitch from 0.74 microns to 0.32 microns. The smaller pits, smaller beam and shorter track pitch together enable a single-layer Blu-ray disc to hold more than 25GB of information about five times the amount of information that can be stores on a DVD.
Single Layer BDSingle Layer BD
• A single-layer BIu-ray disc, which is roughly the same size as a DVD, can hold up to 27 GB of data that's more than two hours of high-definition video or about 13 hours of standard video.
Double Layer BDDouble Layer BD
• A double-layer Blu-ray disc can store up to 54 GB, enough to hold about 4.5 hours of high-definition video or more than 20 hours of standard video.

CONCLUSIONCONCLUSION• Blu-ray disc has been a consistent road map to
emerging disc technologies. Blue-ray can store up to 54 GB, enough to hold about 4.5 hours of high -definition video or more than 20 hours of standard video. And there are even plans in the works to develop a disc with twice that amount of storage.
• It’s very likely that the technology will be adopted as the next generation optical disc format for PC data storage and replace technologies such as DVD+-R, DVD+-RW, and DVD-RAM.
