Sharp has developed a dual layer blue ray DVD disk that will store 100Gb on one side of a DVD disk. They were able to produce a translucent film that reflects enough light for the top layer to be read, while being transparent enough to allow the drive to read/write to a layer below the top layer.
This is a welcome development; with ever increasing hard drive sizes it is becoming difficult to back up entire systems to anything other than another hard drive - backing up 500Gb to 4.7Gb DVD's is simply not practical.
The remaining problem is that the various DVD formats are still competing; personally I hope that people settle on this new format from Sharp - I can use the storage. I wonder how long it takes to write 100Gb to a disk...
