Meanwhile, engineers at the company have
filed a patent
for a disc that could feature up to
different formats on different layers: Blu-Ray, HD DVD, standard DVD, and CD. Each side of a disc can handle two layers, which means conceivably you could have two standards per side. Making discs is certainly cheaper than making hybrid players, which would likely require multiple lasers and chipsets to handle all four of these formats.
There’s no official news from Warner on what their plans are, but they’ve already
released the first HD DVD/DVD combo disc
earlier this year, so no doubt there’s some plan gestating inside the corporate headquarters.
