As an advancement to the conventional 2 D data storage on optical device, 3D optical storage can hold enormous amount of data in the same space.
We live in a world where there is increasing need for higher capacity memory devices.
3 D optical storage can pave the way for new storage drives and memory that can store data much better.
This is looking quite achievable in the next few years .
Computers are sure to get a boost and you will also be free from data storage issues ( if any ) .
