NewScientistTech has reported that two Warner engineers have filed a patent for a triple format disc capable of holding Blu-ray, HD DVD and standard DVD content.
Warner's plan is to create a disc with a Blu-ray top layer that works like a two-way mirror. This should reflect just enough blue light for a Blu-ray player to read it okay. But it should also let enough light through for HD-DVD players to ignore the Blu-ray recording and find a second HD-DVD layer beneath.
An ordinary DVD recording could be put on the other side, so that conventional DVD players can read the disc as well.
Although the triple-standard disc will cost more to make, it should still be cheaper than pressing three, and shops should be pleased not to have their shelves overloaded with so many different discs.
