Blu-ray DVD Combo Disc
Japanese disc producer Infinity on Friday rolled out the world's first production video title to include both Blu-ray and DVD on a single layer. A box for the TV series Code Blue will include playable versions of both formats by using a permeable layer that takes advantage of the different wavelengths to store data at different levels; Blu-ray's namesake laser will recognize one layer, while a DVD player's red laser will see another. The technique lets owners of older movie players and PC drives buy a single title and automatically upgrade to playing HD when they pick up a Blu-ray player.
