Re: Bye-bye tape drives
You can use lasers focused on a 3D-XYZ glass cube to do permanent data writes (i.e. WORM = Write Once Read Mainly) at data capacities as high as a petabyte for a 10 cm per size glass cube.
You're basically popping a nano-sized bubble in a permanent silica media at high laser power and use another much lower power laser to read the data.
It's much more expensive since the glass cubes have to be high-purity low-creep silica + boron glass BUT it's a PERMANENT archive which should last into the MILLIONS of years! And at one petabyte per litre, what media can even come even close to matching that?
