Blu-ray, also referred to as Blu-ray Disc (BD), is the naming of a next-generation optical disc format jointly developed with the Blu-ray Disc Association (BDA), a gaggle of the world’s leading consumer electronics, pc and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format originated equip recording, rewriting and playback of high-definition video (HD), as well as storing huge amounts of internet data.

The format offers more than 5 times the storage capacity of traditional DVDs and may save 25GB on the single-layer disc and 50GB over 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 through the use of 20 layers.

While current optical disc technologies such as DVD, DVDR, DVDRW, and DVDRAM count on a red laser to read and write data, the brand new format runs on the blue-violet laser instead, hence the name Blu-ray. Regardless of the different sort of lasers used, Blu-ray products may be easily made backwards appropriate for CDs and DVDs using a BD/DVD/CD compatible optical pickup unit.

The main benefit of by using a blue-violet laser (405nm) is always that it provides a shorter wavelength over a red laser (650nm), which makes it possible to focus the laser spot with sustained precision. This enables data to become packed more tightly and kept in less space, so it’s possible to fit more data on the disc even though it’s exactly the same size like a CD/DVD. This along with the change of numerical aperture to .85 is what enables Blu-ray Discs to hold 25GB/50GB.

Blu-ray is now sustained by about 200 with the world’s leading electronics, personal computer, recording media, gaming and music companies. The format boasts support from all Hollywood studios and countless smaller studios being a successor to today’s DVD format. Many studios have also announced that they may begin releasing new films on Blu-ray Disc day-and-date with DVD, or a continuous slate of catalog titles monthly.
