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.
