Blu Ray – Set to Take the World

The Blu-ray Disc is a new generation of optical discs. Base of Blu-Ray technology is a blue-violet coloured laser. Reason the new Blu-ray technology makes is possible to store much more information because the wave length is shorter. DVDs and CDs works at a wave length of 650 and 780 nm with based on red and infrared lasers, but the blue laser operates at a wave length of 405 nm.

The laser beam can be focused much more tightly at the surface of the disc and it is means that a smaller spot will be produced on the surface on the disc. There will naturally be room for more information on each disc when the spots become smaller and the minimum spot size of any laser depends on a naturally accruing phenomenon called diffraction. Diffraction will also occur the waves meet an obstruction and we can affect the diffraction with reducing the wavelength of a laser. This is the advantage with the Blu-ray technology.

The lens used to focus the light has a higher numerical aperture can affect the diffraction. Based appliances of Blu-ray technology are also equipped with a dual-lens system of supreme quality. To prevent unwanted optical effects, the cover layer has been made thinner and this makes it possible for a Blu-ray laser to focus on much smaller spots. The Blu-ray disc makes it possible to store even more data because the optical improvements are accompanied with a new method for encoding data.

Blu-ray technology has been developed by Sony and Philips as a joint venture between several major manufacturers of PCs and consumer electronics. Sony was launched the first Blu-ray recorder in Japan but now, Blu-ray technology used Samsung, JVC, Matsushita (Panasonic) and LG Electronics in their products.

The HD DVD format is the main competitor for the Blu-ray technology because capable of storing more information than a normal DVD. HD DVD discs is the tougher if compare Blu-ray disc because the data is stored extremely close to the surface in a Blu-ray disc and this made the first Blu-ray discs extremely vulnerable to scratching. Since 2004, all Blu-ray discs much more durable and will work even after being attacked with a screwdriver because coated with a clear polymer.

Video Player in The Next Generation

Blu-ray disc players is video player in the next generation with high-tech wonders display an amazing 1920 x 1080 lines of high-def resolution. They also feature Java technology and internet connections. When you view Blu-ray movies, BD Java interactive technology give a new experience.

HD-DVD is Blu-ray’s rival. They have been included picture-in-picture features, since the get go however it wasn’t a required part of the Blu-ray technology until October 2006. Blu-ray players must meet minimum hardware requirements including memory storage (at least 256MB of persistent memory) and at least 1GB of storage for downloaded internet content because to meet the demands of BD Java requirements.

Let you watch your HD movies on your own terms, on your own giant screens because Blu-ray recorders equipped with an internet connection to downloading movies.

Blu-ray technology including formats MPEG-2 which is enhanced for high definition as well as for the playback of HDTV recordings and DVDs, MPEG-4 AVC, and SMPTE VC-1 which is based on the familiar Microsoft Windows Media Video technology. Blu-ray disc player will support these video codecs and the movie studios know it. Use whichever codec are the common choices from which to choose and best meets their needs.

Don’t expect all Blu-ray movies to have the sound of your choice because Blu-ray incorporates a variety of audio codecs including the mandatory codecs such as Linear PCM, Dolby Digital, and DTS Digital Surround. It’s purely up to the movie studios to decide what to use. Optional audio codecs include Dolby Digital Plus, Dolby TrueHD, DTS-HD High Resolution Audio, and DTS-HD Master Audio.

About a Blu Ray Burner

Do you have plan for buying the newest movie or video game in Blu-ray format? Everyone push so hard to move over to Blu-ray technology. So pretty surprising has by moving this new format because they really show you the potential video games and movies.

The amounts of space it can hold make the biggest factor as to why this format is so popular. A single layer disc can hold up to 25 GB whereas a dual layer can hold up to 50 GB. You can allow for game and movie studios to release media in high definition with this large amount of space. So make movies and video games much more enjoyable with add many additional features.

A disc could actually hold, a single disc could 9 hours of HD video contents, 23 hours of standard definition video, or you could fit 72 CD’s on a single Blu-ray disc. This is space as the DVD’s used to hold about 4 GB. You can see that they are turning more into movies than games and it means they can use higher quality maps, environments, and can create much larger games.

Getting a Blu-ray burner is a must if you like to backup files and wants the space to hold video content in HD formats.
