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[edit]
The first five-dimensional disc was developed in 2013. This disc could hold just a few kilobytes of data, but was improved to 360 GB of data. Compared to other storage media, 5D discs are more durable. This is because they are made of quartz glass which allows them to handle temperature extremes up to 1,000 °C and survive at room temperature for up 13.8 billion years[dubious ] without losing data.[3][unreliable source?][better source needed]
Advantages over current discs[edit]
5D DVDs use a writing system that uses "nanograting" on which data is being encoded, gathering light that is traveling through the glass providing five dimensions with which to read the system.[incomprehensible][non sequitur][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.[citation needed]
This is impressive[according to whom?] because it can contain more data than DVD and Blu-ray discs which are bigger than the 5D disc yet the 5D can store more data.[3]
