it's not actually 5 dimensions in that sense. a CD works by having small ridges, and when a laser shines on it, it either bounces back as a 1 or a 0, but this can be a 0, 1, 2, 3, or 4, which allows it to store much more information more reliably and is technically 5 dimensions.
But it's still 3 dimensional right? In the traditional sense of the term.

To answer stille20's question yes it is still 3d meaning you still use length width and height to specify a certain position. Just like we usually use latitude longitude and elevation to map our world. The reason this can store more than what we use now is because it will take less digits to represent data which means the physical space you need can be smaller but fit more data on it. Like in binary the number 9081 takes 32 digits to represent, but in the quaternary number system 9081 only takes 7 digits to represent.

I will try to explain a bit better here. So like panthers said a cd uses bumps to reflect a lazer and represent data, where the cd is flat it is a 0 when the lazer hits a bump it is a 1. This is referred to as 2 dimensional because it can either be on(1) or off(0). So these use sort of the same thing. The tiny white dots are on multiple layers , when the lazer hits a dot the lazer strength and position changes which can be be read just like on a cd. The reason this is referred to as 5d is because unlike the cd where there are only two possibilities, this disk has 5 possibilities it uses the light strength, and x, y, and z axes. So that means this can be a 0 1 2 3 or a 4 for a total of 5 possibilities. Hope this helps
At ROOM TEMPERATURE.
When the sun dies, there will be solar flares in which would destroy the crust of the earth. Destroying the data disks along with it.
I have some floppy disks and a Zip disk that I can't read. The problem isn't density or that they didn't last. I just don't have anything that can read a 5.25" floppy or a Zip drive. I picture a couple of these disks...but no drive or whatever to read them.
I first thought, why keep it hidden THAT LONG lol

Drops and cracks.
awwww dammit
