It’s called the Millennial Disc, and it is being marketed as a 1,000 year storage for digital information.
Before we run out and buy a stack of these for our archives, I would simply ask:
How many years before some aspect of this technology – the 5″ 12cm digital storage disc, the disc formatting, the communication channel between the drive and the computer – becomes obsolete?
This is not meant to be a snarky or rhetorical question. The Lunar Orbiter Image Recovery Project has been dealing with those very issues: extracting an obsolete data format from an obsolete storage media using restored obsolete equipment. If the team didn’t have a couple of original machines, and a technician who understood how they worked, the images would be incredibly difficult (approaching impossible) to recover. And this is going back only 43 years.
I used to use CD-ROM, CD-RW, and later the DVD variants, for most of my data exchange. Now it is cheaper, easier, and faster to simply use a USB flash drive. I don’t expect the 5″ 12cm disk to be around longer than 5 or 10 years. Neither should libraries.
Any archival storage should utilize high-quality, durable storage material. There should be a regular, ongoing evaluation as to when the storage media should be replaced. Always keep some old equipment (with old software) around to ensure your ability to convert.
