“A computer disc about the size of a DVD that can hold 60 times more data will go on sale in 2006, according to its American developer InPhase Technologies […]. The discs, holding 300GB each, use so-called Tapestry holographic memory technology to store data by interference of light. They are also able to read and write data at 10 times the speed of a normal DVD.”
Looks like maybe I can skip Blu-Ray and HD-DVD altogether. I even have yet to burn a dual layer DVD!
