Blu-ray, often known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed through the Blu-ray Disc Association (BDA), a gaggle of the world's leading electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format got its start allow recording, rewriting and playback of high-definition video (HD), along with storing large amounts of internet data.
The format offers more than more the storage capacity of traditional DVDs and can deal with 25GB with a single-layer disc and 50GB with a dual-layer disc. This extra capacity combined while using advanced video and audio codecs will offer you consumers an unprecedented HD experience. Recent development by Pioneer has pushed the storage capacity to 500GB over a single disc by making use of 20 layers.
While current optical disc technologies including DVD, DVDR, DVDRW, and DVDRAM count on a red laser you just read and write data, the modern format uses a blue-violet laser instead, and so the name Blu-ray. Despite the different sort of lasers used, Blu-ray products may be easily made backwards suitable for CDs and DVDs using a BD/DVD/CD compatible optical pickup unit.
The advantage of using a blue-violet laser (405nm) is it provides a shorter wavelength when compared to a red laser (650nm), which means that we can focus the laser spot with even greater precision. This gives data being packed more tightly and trapped in less space, so it's possible to match more data on the disc even though it's a similar size like a CD/DVD. This with the change of numerical aperture to .85 's what enables Blu-ray Discs to carry 25GB/50GB.
BD is currently based on about 200 from the world's leading electronics, laptop or computer, recording media, video game and music companies. The format even offers support from all Hollywood studios and countless smaller studios like a successor to today's DVD format. Many studios in addition have announced that they will begin releasing new films on Blu-ray Disc day-and-date with DVD, and a continuous slate of catalog titles on a monthly basis.
