Ritek claims to not only have been able to produce a three-layer and four-layer HD optical discs, but to have successfully designed HD media with a full 10 layers. The company says that its multi-layer process can be applied to both HD DVD and Blu-ray formats.

At base specifications, 10 layers on an HD DVD would yield 150GB, assuming 15GB per layer. For Blu-ray, the total over 10 layers jumps to 250GB, assuming the base 25GB per layer.
