TDK managed to shove a 320 GB disk
TDK engineers managed to create a prototype disk capable of holding up to 320 GB of data. This is about 6 times more than Blu-ray discs can hold (they hold from 25 to 50 GB of information).
TDK presented an analogue back in the 2006th, but then the quality was not good enough. The disc from TDK contains 10 layers of 32 GB each. The first layer of such a disk is created using an alloy of silicon and copper, and the rest from germanium and bismuth. Engineers had to work hard and experiment with materials when creating a prototype disc of such a large volume. By the way, the diameter of the disk is 12 cm (as standard).
Not reported on the timing of the commercial implementation of disks for the world community.
There are even more prototypes: Pioneer last year showed a prototype with a capacity of 400 GB (16 layers). But for me, for some reason it seems that TDK will start mass production more quickly.
