Blu-ray Disc (BD) is developed to enable recording, rewriting and playback of High Definition (HD) video, as well as storing large amounts of data.

The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25 GB on a Single-Layer disc and 50 GB on a Dual-Layer disc.

This means you can store over 9 hours of HD video on a 50 GB disc and about 23 hours of Standard Definition (SD) video on a 50 GB disc.

The name Blu-ray is derived from the underlying technology, which utilizes a blue-violet laser to read and write data. The name Blu-ray is a combination of "Blue" (blue-violet laser) and "Ray" (optical ray).

This blue laser has a much shorter wavelength than the current red laser DVD system, which makes it possible to read and write smaller pits. As a result, Blu-ray Discs can hold more data on a single sided single layer 12 cm disc.
