So, 8.5 TB on a holographic device ?

I think that I have heard this song before.

"The origins of the field date back to the 1950s, when Yehuda Hirshberg
developed the photochromic spiropyrans and suggested their use in data
storage."

Too early for my lifetime but ...

"In 1975, Hitachi introduced a video disc system in which chrominance,
luminance and sound information were encoded holographically."

At least they claim to have advanced something in regards to the UV

a 3.5" floppy wouldn't have been an earlier solution to the UV
problem if that was the only thing holding the technology back.
