  Same here. No progress.

  I'm no expert, but this is a basic explanation of the technology they're studying. https://www.youtube.com/watch?v=CfME3e7aSNk https://www.youtube.com/watch?v=CfME3e7aSNk The paper describes some experiments that are attempting to profile the technology against magnetic storage drives.

  I remember the exact same thing. Might have been this BYTE magazine from 1996 https://archive.org/details/199604_byte_magazine_vol_21_04_future_computers_windows_95_pdf__mlib https://archive.org/details/199604_byte_magazine_vol_21_04_f...

  Very much not an expert, but I think this is talking about a whole different technology. This is holographic storage within a 3-D medium. The article explains that the technology is 20+ years old, but didn't seem to occupy an optimal point on the frontier of throughput and cost, which is the major tradeoff for long-term storage devices. But it says with the physical limits of spinning magnetic disks on the horizon, it's worth looking at holographic again. It further explains that to characterize the cost, you have to consider that the data has to be refreshed periodically, because reading degrades it, so that must be considered in the cost. And then they describe a protocol for doing the reads and refreshes that has good results.
