    The data is laser etched into fused silica. It will not degrade like CDs or DVDs. It will hold its data until something damages the disk.

      Yeah and mass manufactured CD’s are physically stamped into aluminum and then covered in polycarbonate.

      In 20 years some new type of degradation might be observed and people will say, “Oh yeah, we didn’t think of that.”

      For example the etching could start micro fractures from repeated heating and cooling that happens over the long term.
