The world of digital video recording has taken a quantum leap with the blu-ray disc technology. One can safely say that with the blu-ray technology, the quality of digital video recording has finally gone state of the art. It is a whole new movie watching experience on your home theater system.
In pure technical terms, the blu-ray discs use a violet color laser ray that utilizes a short wavelength to allow it to record more data on a 12 cm high density optical disc. The new and improved versions of blu-ray discs are coming with a hard coating on the surface that allows the disc to become far more resistant to scratching compared to other technologies.
One of the best advantages of this technology is that blu-ray discs have incorporated the BD+ anti copying system, which helps to cut down the menace of video piracy to a substantial extent. This became one of the key reasons for the huge backing that this technology received from Hollywood film studios, and eventually led to the global market supremacy of this technology.
