Blu-ray, often known as Blu-ray Disc (BD), is the category of a next-generation optical disc format jointly developed through the Blu-ray Disc Association (BDA), a gaggle of the world's leading consumer 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 was developed allow recording, rewriting and playback of high-definition video (HD), as well as storing huge amounts of web data.
The format offers more than five times the storage capacity of traditional DVDs and can deal with 25GB over a single-layer disc and 50GB on the dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience. Recent development by Pioneer has pushed the storage capacity to 500GB on the single disc by utilizing 20 layers.
While current optical disc technologies for example DVD, DVDR, DVDRW, and DVDRAM make use of a red laser to read and write data, the brand new format works on the blue-violet laser instead, and so the name Blu-ray. Rapidly different type of lasers used, Blu-ray products may be easily made backwards appropriate for CDs and DVDs by using a BD/DVD/CD compatible optical pickup unit.
The benefit of using a blue-violet laser (405nm) is always that it features a shorter wavelength when compared to a red laser (650nm), which makes it possible to focus the laser spot with increased precision. This allows data for being packed more tightly and stored in less space, so it's possible to match more data about the disc despite the fact that it's exactly the same size as a CD/DVD. This alongside the change of numerical aperture to .85 's what enables Blu-ray Discs to hold 25GB/50GB.
Blu-ray is supported by about 200 of the world's leading electronics, personal computer, recording media, video game and music companies. The format also offers support from all Hollywood studios and countless smaller studios as a successor to today's DVD format. Many studios have announced that they'll begin releasing new movies on Blu-ray Disc day-and-date with DVD, and a continuous slate of catalog titles monthly.
