Blu-ray Disc (BD), is the name of the new optical disc format. The format was developed to enable recording, rewriting and playback of high-definition video (HD),
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 25GB on a single-layer disc
and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer our clients an unprecedented HD experience.
While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead,
hence the name Blu-ray. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus
the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it’s possible to fit more data on the disc even though it’s
the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB. Recent development by Pioneer has pushed
the storage capacity to 500GB on a single disc by using 20 layers.
Blu-ray is currently supported by about 200 of the world’s leading consumer electronics, personal computer, recording media, video game and music companies.
This next generation optical disc format provides the experience of the ultimate full high definition of 1080p (Full HD 1080p). That said, it allows for obtaining the best picture quality your high definition television (HDTV) is capable of displaying. It even improves the quality of legacy DVDs; the conversion to the enhanced resolution of 1080p improves the image quality to make it look as good as the full high definition (Full HD) allows best.
Blu-ray uses state-of-the-art laser technology, with up to five times more digital details than conventional DVDs. More details mean more space for great features and other content.
With Blu-ray technology, you can enjoy the best sound available for your entertainment. It supports the latest advanced digital audio formats to deliver breathtaking and realistic surround sound.
