Blu-ray technology refers to the technique used by manufacturers to develop blu-ray dvds . Blu-ray disc (BD) is an optical disc storage device used for storing video, computer games and other forms of data. It has a huge storage capacity, as much as 25 GB for a single layered compact disc (CD). It derives its name from the blu violet laser used to read the content stored in the disc. It uses a short wave length; smaller than the one in use by a standard DVD, but harbors the storage capacity of up to six DVDs combined.
They say that necessity is the mother of invention. blu-ray dvds were developed out of the need to provide an inexpensive device to play high definition content. Prior to its development, devices used proved to be highly inefficient and cumbersome. After the development of the blu laser diode, a project named 'DVR blu' was started whose focus was the development of rewritable discs. These discs would eventually be remodeled to become 'Blu-ray' discs. The inaugural Blu-ray discs were availed to the public in Japan only. However, this product lacked standardization for video recording and as a result, the major movie companies would not accept it.
Eventually the blu-ray standardization was developed. Subsequently a hard coating polymer for Blu-ray discs was invented. Because of this, the cartridges were no longer required and they were discarded. Blu-ray-Read Only Memory (ROM) discs were finalized during the same period. The earlier versions of the Blu-ray discs used the same technology used on standard DVD. However, modifications made on the discs greatly improved their storage capacity and allowed the commencement of movie storage using a 50 GB dual layer disc. Researchers eventually developed a product for the mass market. The Blu-ray disc was to be used on personal computers and was equipped with both single layer and dual layer capability.
blu-ray dvds faced stiff competition from High Definition (HD) DVDs. The HD DVDs had a more effective marketing strategy that made the Blu-ray discs seem expensive and cumbersome. However, they got a respite with the development of the third generation play station since it also functioned as Blu-ray disc player. With the passage of time, blu-ray discs outsold HD DVDs when mainly youngsters but also the general public purchased the third generation play station for entertainment.
Subsequently, the straw that broke the camel's back as it were was the decision by major movie houses to start using Blu-ray discs as opposed to HD DVD. This affected the operations of the manufacturers of the HD DVDs because movie houses were a significant market for their product. This action by the movie houses was followed by a decision among major retailers to stop stocking HD DVDs. After this development, the manufacturer of HD DVD stopped the production of this product.
Many observers credit the development of the third generation play station together with the superior marketing techniques employed by the proponents of the Blu-ray discs as the trigger that precipitated the sudden rise of the blu-ray dvds and consequently the fall of the HD DVDs.
