HD disc wars to be settled by hybrid disk?

On the one hand, you have the ability to remove the oncoming format battle altogether and ensure that your disc will play on whatever hardware you choose to buy. On the other, you have all that…

Inventors have come up with a design for a disc that can store copies of films in rival high-definition formats.

A US patent has been filed for the discs that could hold both HD-DVD and Blu-Ray versions of movies.

Currently movie makers and technology companies are dividing into camps that back either one or the other of the two formats.

The creation of the discs could end the looming battle over the different high-definition formats.

The design of the disc patented in the US would have three layers. One for a standard DVD version of a film and then one for each of the competing formats.

The innovation is thought to be possible because the rival formats store data on the discs at different depths.

Using reflective films should make it possible to store data for one movie format in one layer but to see through that, if needed, to the deeper layer which has the same movie in the rival format.

This was slightly unforseen. I'm actually slightly conflicted about this. On the one hand, you have the ability to remove the oncoming format battle altogether and ensure that your disc will play on whatever hardware you choose to buy. On the other, you have all that storage potential effectively ruined by a need to duplicate the data. I'm not entirely sure thats a happy compromise.

Of course, you have to wonder whether it would be cheaper to just produce three seperate disks...
