TDK, a company that produced a prototype 200 GB Blu-Ray disc way back in 2006, has unveiled a new prototype before the 200GB has even seen the light of day. This time, it is a 10-layer Blu-Ray disc capable of even more storage.

The short version: this can be used in consumer products.

What’s great about this latest development in optical media, besides the awesomeness that say a 320 GB Metal Gear Solid or Final Fantasy or Grand Theft Auto game would bring, is that according to TDK, “it is possible to write and read data on and from the disc by using a blue-violet semiconductor laser with an oscillation wavelength of 405nm and an objective lens with a numerical aperture (NA) of 0.85, which are currently used for the Blu-ray disc.”

This has been a trend in newer, higher-capacity Blu-Ray discs. Due to the proliferation of internet connections everywhere and firmware being written to non-volatile (update-able) chips, it means that our PlayStation 3s may simply be a firmware update away from reading these 10-layer behemoths of Blu-Ray discs. Although we have yet to have seen even a 100 GB disc out on the market, we may see the first one before too long.
