No really
TOP BOFFINS say they have hatched out a way to stick 200,000 DVDs on a single disk.
Professor Min Gu and his team at Swinburne University of Technology’s Centre
for Micro-Photonics are three years into a
five year project that is looking at how nanotechnology can be used to
exponentially increase the amount of information contained on a single disc.
The target is to get a petabyte of data on a single disc. This is about 20,000 times greater than a Blu-ray Disk. His big idea is to incorporate nanostructured material onto a standard CD or DVD sized disk.
Another one of the boffins, Dr James Chon said that a typical CD is about 1.2 millimetres thick, the information recorded on it using what is now standard technology takes up less than a micron of the CD’s thickness.
However you can stack up multilayers to increase the amount of data and Professor Gu's team have increase storage capacity up to 52 layers. The theory is that they can go up to 200 and 300 layers. µ
