Blu-ray players will soon become a thing of the future with many people already becoming vastly interested in them and casting aside their DVD players. Blu-ray is basically a high definition alternative to DVD’s so you can watch films in crystal clear format and a higher resolution.
The first blu-ray disc titles were released back in June 2006 and are still gradually making their way into the limelight and the international market as only a selected amount of people understand what they are, the benefits of them, and of course the money to actually purchase one of these devices.
The disc itself is the same size and shape as a DVD disc, the only difference is blu-ray uses a blue laser to read and write, and this laser has a shorter wavelength from its beam than that of a DVD so the ability to store more on the disc is possible, DVD’s use a red laser to read and write with a longer beam length so storage potentials are limited.
At the moment the rewritable discs come in at anything from a dual layer disc that holds 25GB per layer, so 50GB altogether, and right through to Riteks latest development where they have successfully developed a 10 layer disc that reaches the boundaries of 250GB.
A lot of films that are currently being released are also being developed in the Blue-ray form which means you can watch these on a blu-ray player in HD, and surprisingly the prices of a blu-ray disc are very reasonable. For example, if you wanted to buy Batman: The Dark Knight you can be looking as cheap as £14.99 for the blu-ray format. That said, for a decent blu-ray player you can expect to pay anything from £150 – £300.
