The Blu-ray Disc belongs to a new generation of optical discs capable of staging high density data. Blu-Ray technology is determined by a blue-violet coloured laser. The blue laser operates at a wave length of 405 nm, whilst older technology for example DVDs and CDs are depending on red and infrared lasers that works at 650 and 780 nm. Given that the wave length is shorter that has a blue laser, the new Blu-ray technological innovation makes is possible to shop much a lot more facts

The advantage with the Blu-ray technology is that the laser beam can be focused a great deal more tightly at the surface of the disc. Tight focus means that a smaller spot will be produced within the surface within the disc, and when the spots turn out to be smaller there will naturally be room for far more facts on each disc. The minimum spot size of any laser depends on a naturally accruing phenomenon named diffraction. The narrow beam of light sent out from a laser will always diverge into a wider beam eventually, due towards the natural diffraction of waves. Diffraction will also occur the waves meet an obstruction. By reducing the wavelength of a laser, we can affect the diffraction.

In Blu-ray engineering, the diffractions is also affected by the fact that the lens applied to focus the light has a higher numerical aperture than the lenses discovered in ordinary DVDs – 0.85 rather than 0.6. Blu-ray engineering based appliances are also equipped having a dual-lens system of supreme high quality, as well as the cover layer has been produced thinner so that you can prevent unwanted optical effects. All this tends to make it doable for a Blu-ray laser to focus on significantly smaller spots. The optical improvements are accompanied with a brand new technique for encoding information which can make it probable to store even far more data about the Blu-ray disc.

The standard for Blu-ray technologies has been developed as a joint venture between several major manufacturers of PCs and consumer electronics, including Sony and Philips. The group is named the Blu-ray Disc Association (BDA). The first Blu-ray recorder was launched in Japan in 2003, by Sony. Nowadays, Samsung, JVC, Matsushita (Panasonic) and LG Electronics are all examples of companies utilizing Blu-ray technology in their products. Hewlett Packard has announced that they will release desktop PCs equipped with Blu-ray technological innovation in late 2005.

The main competitor for the Blu-ray technology is the HD DVD format which is also capable of storing far more details than a normal DVD. The Blu-ray technology does however enable for far more details per layer than the HD DVD format – 25 GB compared to 15 GB. The Blu-ray technological innovation will on the other hand most likely be more expensive to support, at least initially, which can make the HD DVD a tempting alternative. In a Blu-ray disc, the data is stored very close towards surface. This produced the primary Blu-ray discs extremely vulnerable to scratching and a lot of users preferred the tougher HD DVD discs. Given that 2004, all Blu-ray discs are coated with a clear polymer named “Durabis” which creates them a lot more durable. According to the developers of Durabis, the TDK Corporation, a coated Blu-ray disc will work even after being attacked with a screwdriver.

It used to be a simple choice: cassette or CD. Then it was VHS or DVD. Now, the great leap forward is Blu-ray. Yeah, that’s right. Blue-ray. It sounds fancy, like its got some kind of special sauce that is going to transform your life and maybe for once, it might be true. For someone who appreciates the hiss and pop of vinyl, it is hard to make the case for any kind of new, improved media format.

People loved the CD when it hit the markets. It was sleek, chrome-colored and reminded us of that circular beauty: the LP. The improvement from clunky cassettes was visible. People could see how they cold save space, enjoy the album artwork, and jive to the jumping digital sound. The same jump was evident with VHS to DVD.

The hefty clamor of the VHS tape seemed like some relic from the Fifties when you compared it to the elegance of the DVD. When people can see how a new technology can impact something as simple as the space they can save, they will go for it. The reduction of size and maximizing of space is a great sell. The improved audio and visual experience is icing on the cake.

Hence the problem. This is why the Blu-ray has been a slow sell so far. Its not that the Blu-ray will save you any more space than the DVD. In fact, their dimensions are nearly identical. The proof, in this case, is in the pudding and that makes for a hard sell. You have to rely on word of mouth campaigns to get people interested in updating their entire music and movie catalogue to keep up with the Jones.

Most Blu-ray collections, especially the Disney Blu-ray line, offer superior sound and film playback. It’s that simple and the reason why it’s so hard to get people moving on them. You have to watch a Blu-ray movie to appreciate the great leap forward in 35mm compression rates and Dolby 5.1 soundtracks. That’s the slow build and slow burn of getting onto the Blu-ray bandwagon. Once people see it for themselves, they’ll make the leap.

If you are looking to jump on board the Blu-ray bandwagon, you can’t do much better than the Disney Blu-ray collection. It’s got some of the best features and most exclusive bonus features around.
