I see these pop up every now and then with obscure video programs recorded with printed labels, and that rainbow 3M cover. Did anyone deal with them back then? It seems they did low print runs but I'm curious about numbers including prices and minimum number of discs.

I’d assume that’s a promo, a test pressing, a recordable, etc. It’s not retail. The “low print run” is probably like a dozen or three…or even one.

We are very lucky to have this page archived: Imation Laser Videodisc page. Pricing can be seen by clicking the Alpha Disc link.

Here is a video of when Imation was still 3M:

Thanks! That was very informative. So those 3M custom discs go back as far as 1984.
