As You have read, scientists working on this project are even from Russia. I am from Russia and already read about this project month ago in some Russian computer-related newspaper. They already developed a 8-layer drive. I seen the image - it's a deck-sized drive with disk-loader in the middle, and eight light-diodes on the front. Technology is based on the property of some material to 'remember' that it was lighted by laser of specified frequency. Laser spot is _very_ small during the recording. When we want to read the information, we may light it with the same frequency laser spot, but it may be larger than the recording. Recorded areas a fluorescenting and the area around the laser light spot is digitized by the CCD camera, and then processed to determine the layers and read the data.
