Super 5D DVD
New DVD format records information in 5 dimensions!! Yeah you heard me alright! 5Dimensions!
A new “five-dimensional” recording system for DVD-sized discs that can store 1.6TB of data (compared with Blu-ray’s current 50GB limit), able to store 300 movies, 250,000 songs and leap tall buildings with a single bound.
Many technologists have wondered what format of optical disc will inevitably come to replace the current generation of HD and BluRay DVDs. While there has been no shortage of new formats developed and considered, a new design has been gaining attention as a conceivable, and realistic possibility for the future.
Building on Pink Floyd's research into lasers (joke), the new format is called "5D DVD" and on these DVD-sized discs, up to 1.6 TB of data can be stored utilizing 5 dimensions.
sing nanometre-scale particles of gold as an inscription medium, data is burnt on to the optical discs using lasers that burn information similiar to a regular DVD process involving the 'regular' three spatial dimensions. With 5D DVD however, the recording process doesn't stop after the 3D is done.
Because of the "gold nanorods" color -- which is determined by electromagnetic wavelengths -- can also be used as the fourth dimension of information encoding on the 5D DVDs. The '5th D' is polarization: the surface can be altered to adjust the angle that light hits the disc, so this in turn adds a much greater capacity to the DVDs by allowing for information to be stored in all 5 of these ways.
Go go Australia's Swinburne University of Technology!!!

other than an entire pc backup it sounds really useless (and like it would take forever to burn to)...perhaps if they made the discs really small in physical size (like 1 inch) and cheap (like $1.50 a disc) but with the capacity of a dvd (say 4 or 5 gigabytes) it would be a good idea. At this point in time people don't need more storage space they need faster or smaller (physically smaller i mean) storage. that said, it still sounds like a cool idea.
