5D DVD

A 5D DVD is an optical disc being developed by Peter Zijlstra, James Chon and Min Gu at the Swinburne University of Technology in Melbourne, Australia.[1][2] In 2009, the developers estimated that the technology could be commercially ready in five to ten years.

Background Information

The first five-dimensional data storage unit encoded into a small disc was developed in 2013. This storage unit could hold just a few amount of KB data, however now disc can hold up to 360 GB data. Compare to other storage units, the 5D are more durable. This is because they are made of glass which allows them to be in temperature up to 1,000 °C and survive 13.8 billion years without losing data.[3]

Advantages over current discs

5D DVDs use a writing system that uses "nanograting" on which data is being encoded, gathering light that is travel through the glass providing five dimensions in order to read the system. (This is also called "femtosecond laser writing."[3]

According to the developers, this could result in discs with a capacity of 10 terabytes, approximately 2000 times the capacity of a standard DVD, compared to Holographic Versatile Disc technology, which has an estimated maximum disc capacity of 6 terabytes. The similarity of disc writing would also make it easier to make 5D DVD players backwards-compatible with existing CD and DVD technology.

This is impressive because it can contain more data than DVD and Blu-ray disc which are bigger than the 5D disc yet the 5D can hold more storage.[3]
