In light with the magnitude from all of the discuss digital this and hi def that, there are tons individuals wondering what are the differences are relating to the HD DVD format and Blu ray. Here in a nutshell could be the scoop that may define the technical differences between these two. As a side note, inside Format War that ensued until 2008 between your formats, Sony while using Blu ray won when Toshiba announced that it would no longer be making HD DVD players after Warner Bros. switched for the Blu Ray format.
Both Blu Ray and HD DVD have the identical wavelength which they usage of 405nm, and both work with a blue violet laser, however the optics are very different. The Blu Ray discs possess a tighter track pitch as opposed to digital discs, in order that they hold much more information even while using laser being a similar wavelength. With a tighter track pitch, this means that the BD has a single thread of knowledge that spirals from the inside from the disc outward that’s smaller than the usual pitch that’s less tight, so more thread fits on it.
A lots of people have wondered why, once they use the same form of lasers, the 2 formats incompatible with opposite players. A Blu ray disc (BD) cannot use on a HD digital disc (DVD) player because from the track pitch which was mentioned. Digital discs also use a different surface layer than BD. HD DVD runs on the 0.6mm surface layer, which could be the same as an everyday digital disc, but BD has a much smaller layer (0.1mm), and so the laser focuses during this aperture.
ดูซีรีย์เกาหลี possess a special hard coating, called Durabis, which is placed on make sure which they are resilient to safeguard your data that’s only 0.1mm below its surface. There is an extra help to keeping the layer of data that close for the surface, and that’s that there are more room for really layers and more data that can be put on them then on a HD DVD. The price of BDs is more expensive than their HD counterparts because new products are accustomed to cause them to become; the machines that will make DVDs cannot make BDs because of the different coating, the info layer, and also the track pitches. The bottom line here which is everything about the technical differences between both of these kinds of formats is that this Blu ray discs will set you back, in addition they hold more data.
