How it works While current optical disc technologies such as DVD rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence it’s name Blu-ray While current optical disc technologies such as DVD rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence it’s name Blu-ray The discs come in single or double layer. Single layer can hold 25GB and double can hold 50GB of data compared to DVDs holding 4.7GB of data The discs come in single or double layer. Single layer can hold 25GB and double can hold 50GB of data compared to DVDs holding 4.7GB of data

How it works The benefit of using a blue-violet laser is that it has a shorter wavelength than a red laser, which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD.

Playstation 3 If the PS3 is roughly as successful as Sony's past consoles, that would mean somewhere around 100 million Blu-ray players in homes all over the world in around five years or so, not counting standalone players.

So will Blu-ray last? My opinion is yes. Prices will go down in the near future for both Blu-ray players and HDTVs. Once you experience it, you will not want to watch another movie or TV show in standard definition. My opinion is yes. Prices will go down in the near future for both Blu-ray players and HDTVs.
