TDK shows off 100GB Blu-ray drives

BLU-RAY is the standard that can accommodate more data than a HD DVD but it requires blue laser and it's more expensive to build. It still manages to push some limits.

At Pepcom, a pre-CES show, we found out that TDK has recording media prototypes that can store as much as 100GB on a single disc.

Its Blu-ray discs can sport four layers, each able to store 25GB pre layer. That gets you to whopping 100GB.

At this point HD DVD is limited to 30GB or 15GB per layer on its two layers. In Dual sided discs may up total capacity to 60GB.

25GB BD-R discs are a long way from shipping and it will probably be a couple of years before you will be able to buy 100GB Blu-Ray media.
