Hi, they are simply an "advanced" type of digital support that can contain lot of data. Like DVD was like an advanced CD, now there is Blu-Ray Disc. It's called this way because the laser they use to write and read that disc uses a blue light. For this reason you can't see them in your old DVD reader because the "old" laser is red and it can read the data. PS3 can also read them. Now most movies are sold as DVD and also as Blu-Ray Disc so they can contain larger files and a great quality. Anyway they are still expensive and to appreciate their power you also need a good Home Theater with HD-Full screen and things like that.
