Detailed explanation-1: -Blu-ray Discs (or BDs) are optical discs used for storing data, movies and video games. Blu-ray Discs are the natural successor to DVDs, thanks to their vastly increased storage capacity and the fact that they’re the same size as DVDs and CDs, which allows for easy backwards compatibility.
Detailed explanation-2: -Blu-ray discs can hold more information than other optical media, because of the blue lasers that the disc drives use. A single Blu-ray disc can hold up to 25GB of data. Dual-layer Blu-ray discs will be able to store 50GB of data-equivalent to four hours of HD content.
Detailed explanation-3: -Blu-ray uses a different type of laser to read the discs, allowing a single disc to store more data. As Blu-ray can store more data, it can provide a much better picture and audio quality compared to the DVD format. The best blank Blu-ray discs have large capacities and can be written quickly.
