I feel like I've been reading about variations on this concept (storing data in crystals using a pair of lasers) for my whole life. I've never seen articles about anything other than research stage work though... no companies trying to commercialize, no engineering prototypes, etc.

I could just have missed them, but the longevity of the idea compared to lack of product makes me wonder what the hold-up is... too expensive to make? Bad data transfer rates?

On its surface (pun not intended) a super long-lasting high capacity, write-only storage medium seems to have all sorts of good use cases, so I can't imagine a lack of demand would be a problem.. without some deeper technical holdback.
