So what's the tech behind this one?
It claims to be superior, although similar to Holographic versatile disks with claims of up to double the capacity. How does it achieve this? Nearfield optics? Anyone know?--Spectatorbot13 (talk) 15:53, 26 June 2009 (UTC)
- Read the sources. As I understand it, it reads data from several different layers, and through different polarizations, using three different colours of lasers (instead of current DVDs and Blu-Rays that only use one colour) and thus create multiple different densely-packed layers each readable only by one, or a combination of, the different lasers. In short, with miniaturized data points and all, it's like packing several DVD layers into much less physical space. --BlueSquadronRaven 22:24, 26 June 2009 (UTC)
Graphene-based holographic optical disc created
The team from Swinborne university, mentioned in the wiki page, has produced a protoyte holographic disc. This new information should probably be included in the wiki page.
