Talk about floppy! These new "blue-violet laser" disks is actually made of a very thin film and hold about 9.4 GB on each side. The really draw is that they've figured out a way to put 100 of these in a cartridge for almost a terabyte of storage.
The disks are recordable and there are plans to make a blue-laser version of these to offer up to 5 TB in one cartridge. Not available to us average Joes yet, but keep your eye open. Maybe this will be the next Bernoulli disk!
