Every time an animation film is released or a big budget film is released, we get to know about the Blu Ray 3D DVDs of the same being made available for customers who can get their copy and keep for personal usage. People rush to buy the same. This is because buying a Blu Ray disc of the film means that you are assured of high quality film viewing experience unlike regular DVDs or VCDs.
A Blu-ray 3D, the term stands for the technology which is superior to the DVD format. It is an optical disc storage medium which is used to store high definition film or video. A blu ray 3D can store data up to 20-25 GB per layer and if it is a dual layered disc, it can store about 50 GB of high definition data. Yet, the storage capacity of a Blu ray 3D disc can go up to about 200 GB at times. There are 100 GB Blu ray discs available in the market as well. While the Blu ray discs are much superior to the likes of DVDs, they all look the same.
But why is it called a Blu ray 3D disc? This is because it was coined from the term blue-violet laser which is used to read the discs. A Blu ray uses a wavelength shorter, 405 nanometre to be precise, than a regular DVD which needs a 650 nanometre red laser wavelength. Yet, it has the capacity to store high definition data ten times more than a DVD. To prove its worth, there was a format war held in the past, where the Blu ray discs competed with the regular DVDs and end the result was that the Blu ray discs won hands down!
Before Blu ray, a DVR Blue prototype was unveiled at a technology exhibition. But later in the year, the project was renamed and announced as Blu ray. And this high definition storage disc was created by a nine member team!
It was made available to the consumers for the first time in 2003. The pricing for the Blu Ray player was very high initially yet they did not have any sample video or movies to run on it then. Hollywood had still not accepted this technology as there no management backup to this. Hence a Blu ray disc association was formed in association with 20th Century Fox Studios. Further specifics required to market the product were defined by 2006.
By 2009, many big names in the electronics world launched their own Blu ray 3D disc players. It is developed in association with the BDA which now represents the interests of the electronics, hardware and film making sphere. Given the high quality film experience it offers, it has soon become a household name and people prefer buying a Blu ray disc over any CDs or DVDs available in the market. There is no known technology surpassing Blu ray at the moment. These can be bought online as well as at selected stores.
