_ hd type dvds but called bluray and the disc is blue bluray dvd players are like normal dvd players but use a blue laser instead of red. this is because it has a far shorter wave length so can read smaller bumps and grooves, and so the dvd can have more memory (because all the info can be squashed together ) blu ray is used for high def. films etc. because they need lots of memory Jus thought I would add that the DVD is not Blue, only the laser. different format then hd dvd but pretty much the same. exactly same scenario as betamax/vhs. toshiba and microsoft make hd dvd. samsung, sony, panasonic and many more use blu-ray. hold on a few months till you buy. see what emerges as better. blu ray only have a dozen dvds buy xmas and the players( only 2 made) are 1000 and 1300 pounds. the ps3 will have a blu ray player and is only 500quid and a games console included. The name Blu-ray is derived from the blue-violet laser used to read and write this type of disc. Because of this shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the common DVD format, which uses a red, 650 nm laser. In comparison to HD DVD, which also uses a blue laser, Blu-ray Disc has more information capacity per layer (currently 25 GB, but test media is up to 33 GB). However Blu-Ray discs are expected to be more expensive than HD-DVD discs, at least initially. Sony has released 50 GB recordable BDs and will soon be releasing 50 GB rewritable discs.
