Technologies have come a very long way of earlier times years and has altered the process where people vie their movies. You'll be able to probably remember the days when people watched their home movies through their VCR's. Naturally these VHS tapes were bulky, consumer a lot of storage room, and output much lower quality visuals than seen today with DVD's as well as the emerging BD media. LaserDiscs's soon thereafter replaced the VHS and VCD's however, this was short-lived when DVD was unveiled in the scene. DVD (Digital Versatile Disc) was needless to say considerably more advanced than VCD and stored six times more info.
An individual DVD with a storage capacity of four years old.7 GB can do storing one full-length movie and various behind-the-scene footages as well as other extra features. Because of this, DVD's also have a serious influence on the show industry and as a result more folks are purchasing DVD's to view in their homes. The DVD may however get replaced by the new technology that would further boost the movie industry. The new Hd media technologies are called Blu-ray.

Blu-Ray Discs or BD can record, store and are able to play-back more video, digital audio, along with data. BDs also can store an entire length high-definition movie which in turn needs a higher bandwidth and space for storage. In comparison with DVDs. Blu-Ray Discs contain the edge over the volume of information it can easily store. A single-layer BD has the ability to store 27 GB of digital information. A blu-ray disc has such a large capacity in comparison to DVD in that the power to hold up to 13 hours more of standard video. A double-layer BD on the other hand can be in a position to store more than 4.5 hours of high-definition video because of its 50 GB storage capacity.
Laser lighting is effectively the way in which optical disc storage media (for example DVD and Blu-ray) can read information, with Blu-ray utilizing blue violet rays whereas DVD uses red ultraviolet rays. The amount of information which can be kept in discs depends on how big and precise the laser light is. Blue laser features a shorter wavelength than that of red laser and due to this, blue laser is a bit more precise and can write information in more compact spaces. This is the reason why much more information might be held in a Blu-Ray disc.
A massive storage capacity is not only advantage of a Blu-Ray technology. Blu-Ray Discs may also transfer information at the higher rate. Blu-ray discs are so revolutionary because they are competent at an information transfer rate of 36 Mbps (megabits per second) whereas a standard DVD could only transfer for a price of 10 Mbps.
Two technologies namely, Blu-ray and also Definition DVD (HD-DVD)are in direct competition to successfully get to be the official storage medium in the future of high definition media. Blu-Ray discs were first utilized by Sony inside their Ps3 games websites as bad this, BD is now becoming popular among giant movie production studios like Warner Brothers which have mentioned that they're going to only release their High Definition movies in BD formats starting May of 2008.
