Great news for those who have both Blu-ray and DVDs in the house; Infinity Storage Media has released the first hybrid Blu-ray and DVD disc in Japan. The new media has a total storage capacity of 33.5GB and is compatible with existing DVD and Blu-ray players. The biggest advantage of the new media is backward compatibility – you can play it on…
How does it work?
Based on JVC’s 2004 Blu-ray/DVD combo disc technology, Infinity has layered one format on top of the other on the same side of the disc, making it possible for the lasers to penetrate to the desired depth and read the required information.
The Blu-ray makes up the top layer (25GB) with two more layers beneath that make up the DVD layers (8.5GB). Separated by a semi reflective film, the blue laser accesses the top layer and bounces off the DVD layers, while the red laser penetrate the various layers to get to the DVD information underneath.
The company claims that it has achieved compatibility with 99 percent of tests made on 64 Blu-ray and DVD players and conforms to the Blu-ray Disc specifications released by the Blu-ray Disc Association.
As we mentioned earlier, technically, this is not new. In 2004, JVC released a prototype [PDF], but ISM is the first company to take the disc to production, and hopefully to the masses. The only disadvantage? Currently it’s only available in Japan, and no release date has been set for the United States.

Thats cool, I’d like to buy blurays and play them on my DVD player, then get the bonus of hidef version if and when I get a bluray player. Sounds like win win to me.
There is no way this is bad. HD-DVD combo discs were great. Blu-ray players are expensive, but pretty much everything now plays dvds. I dont have a blu-ray player in every room so i could just flip the disc and play the dvd in my dusty original xbox in my room.
