The Blu-ray disc is an optical storage disc used for storing HD information: movies, games and any other pieces of data. Its main competitor in this area was the HD DVD. A major role in this confrontation was played by the launch of the PlayStation 3 console in 2006, which supports the “blue” disc and which also acts as a Blu-ray disc player.
But the novelties brought about by the Blu-ray disc and implicit by the Blu-ray technology doesn’t stop at that. If a HD DVD can hold up to 60 GB of information – that means 15 GB per layer, the “blue” disc has a limit of 200 GB and the possibility to store 25 GB of data per layer. Up to now was released on the market a Blu-ray disc with a maximum capacity of 50 GB, but for the future it is planned to make available a “quad-layer” version – with 100 GB and even a 10 layer disc with the capacity of 250 GB.
For the time being the “blue” disc is sustained by various large companies and by the biggest movie studios: MGM, Walt Disney, Warner Bros, Buena Vista and many others. The good news are that the price of a player has dropped from 3800$ (one of the first available Blu-ray players) to a medium price of 200$ and that now are available many models of “blue” players produced by different companies, such as: Pioneer, Samsung, LG, Loewe, Panasonic and (of course) Sony.
