Blu Ray (BD) is an optical disc storage medium was designed to supersede the DVD format. The plastic Blu Ray disc the same size as DVDs and CDs, but provides noticeable differences in the definition and quality of the picture. Blu Ray discs contain about 25 GB per layer, and dual later discs (50 GB) are the industry standard for feature-length videodiscs.
The name Blu-Ray Disc refers to the blue laser used to read the disc, which allows a higher amount of information to be stored in a greater density than what is normally possible for red-wavelength laser that is largely used for DVDs.
The first Blu-Ray prototypes were released in October 2000, and the first prototype players were released in 2003. The official release of the Blu Ray on commercial shelves was in 2006, and by 2008, over 2,500 Blu-Ray disc titles were available in Australia and the United Kingdom, with 3,500 of those players being in the United States and Canada. In Japan, there were over 3,300 titles released in Blu-Ray format by 2010.
In today’s time, on the even of 2014, any are curious as to what will be the next video format to take the torch and blaze a trail into the future of movie-viewing at home. It is speculated that Sony and Panasonic may be teaming up in order to carry that torch together.
Where Blu-Ray is capable of holding about 25GB per layer, the discs that Sony and Panasonic claim to have in the works is purported to be able to handle up to 300GB per layer with minimal issues by the end of 2015, enough storage space to outdo the Blu-Ray disc nearly sixfold.
Sony has been pushing 4K ultra high definition (UHD) movies for some time now, which is up to four times the resolution of a 1080p video, in cinemas and high-end TVS. A 4K film is going to likely require about 100GB of legroom to full display its splendor in a resolution worthy of it.
There is still the question as to whether or not optical discs can still compete in an industry that is largely dominated by Netflix, Lovefilm and cloud storage. While it is indeed the successor to Blu-ray, the 300GB isn’t exactly all about films and TV shows. Sony and Panasonic are also discussing the possibility of storing raw data, which may range from an average resident’s home movies to data that can be stored for strictly business purposes.
Optical discs have excellent properties to protect them against the environment, such as dust-resistance and water-resistance, and can also withstand changes in temperature and humidity when stored. This capability allows inter-generational capability between different formats, serving as a measure of insurance that the data can continue to be read even as formats evolve into more advanced forms over the years.

There are some 179 million discs that were sold in the UK last year according to the British film institute. While it’s a drop in 14 percent from the previous year, those selling discs still managed to profit over six times more than the people marketing video-on-demand services.
Sony has managed to remaster its selected classic films into about 4K for theatrical distribution, including Ghostbusters, Taxi Driver and two Spiderman movie; there have also been 1080p versions released on Blu-ray, though there have been very few opportunities to watch them in true 4K.
In the recent years with the increasing need for archive capabilities, not just from video production industries, such as motion pictures and broadcasting, but also from cloud data centers have increasingly large volumes of data following the evolution in network services. Sony and Panasonic’s promises just may be the ticket to set the new standard for next-generation high-capacity optical discs.
