Blu-ray, often known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed with the Blu-ray Disc Association (BDA), a group of the world’s leading electronics, laptop or computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson).

The format offers more than five times the storage capacity of traditional DVDs and may hold up to 25GB on the single-layer disc and 50GB on a dual-layer disc. This extra capacity combined if you use advanced video and audio codecs will give you consumers an unprecedented HD experience. Recent development by Pioneer has pushed the storage capacity to 500GB with a single disc through the use of 20 layers.
While current optical disc technologies such as DVD, DVDR, DVDRW, and DVDRAM depend on a red laser you just read and write data, the newest format uses a blue-violet laser instead, hence the name Blu-ray. Rapidly different sort of lasers used, Blu-ray products can easily be made backwards appropriate for CDs and DVDs by using a BD/DVD/CD compatible optical pickup unit.
The main benefit of by using a blue-violet laser (405nm) is it features a shorter wavelength when compared to a red laser (650nm), which means that we can focus the laser spot with increased precision. This gives data to be packed more tightly and trapped in less space, so it’s possible to suit more data around the disc though it’s a similar size like a CD/DVD. This with the change of numerical aperture to .85 is exactly what enables Blu-ray Discs to keep 25GB/50GB.
Blu-ray is currently sustained by about 200 in the world’s leading consumer electronics, personal computer, recording media, computer game and music companies. The format also offers support from all Hollywood studios and countless smaller studios as being a successor to today’s DVD format. Many studios have announced that they can begin releasing new films on Blu-ray Disc day-and-date with DVD, or a continuous slate of catalog titles each month.
