Could we see a 200GB optical disc? TDK is working on such a project, and recently has made progress that allows them to squeeze an incredible 200GB of data onto a single disc. Originally just a rumor from them, then later a product with "eventual" release, it may arrived much sooner than exepcted. Utilizing 6 layers for data (50GB Blu-Ray discs use 2 layers), TDK has found a way to get a large amount more of data onto a single layer than before, also bringing in the potential for cheaper discs that are above 50GB but below 200GB in size. Then again, current gen drives may not even be able to take advantage of such a disc. But who would be surprised by that?
