This high capacity has been obtained increasing the number of layers on the disc. The disc was revealed at CEATEC JAPAN 2007 by Hitachi, and there is also a workaround to develop an eight-layer variant of the technology to obtain 200 GB capacity on a single sided disc.
According to Hitachi, this quad-layer disc will be fully compatible with existing devices only with a firmware update.

err...readability
Lets see how long it takes to get these discs to market..at a realistic price.....if they ever make it. Lets say Hitachi has gets 90% yield per later. 4 layers = 66% overall yield. Not very cost effective. More layers always = more costs...do the math..I know your all smart enough....... 
Happy Birthday to you
