Researchers at the University of Southampton in the UK successfully stored the entirety of the human genome sequence onto an indestructible 5D optical memory crystal no bigger than a penny. The indestructibility claims are no joke since the discs can withstand temperatures up to 1,000°C, cosmic radiation, and even direct impact forces of 10 tons per cm2.
Yeh, axis was the wrong term. I was thinking degrees of freedom.
However, I misunderstood the concept.
The extra dimensions are basically optical manipulation, like the other comment says with the red and blue lenses.
I thought it was more about the crystals attitude. So in addition to x, y and z, you also have alpha, beta, gamma.
Which would be 3 dimensions/axis with 6 degrees of freedom
