Wow, thank you so much!

I have an interest in this from several points of view. I like photography, in particular on film, I have a modest Laserdisc collection and I am interested in the history of that format. Presumably the images are in "CAV" format, which means they would be perfect still images on a TV set and also searchable by index. IIRC 9999 images could be searched on a single Laserdisc. (But maybe more, certainly the format is capable of holding many more images per side, IIRC 50 000 images per side, but maybe not in individual indexes.)

Also the Laserdisc existed in a write once, read many format - rather similar to CDR technology, but of course analog and very expensive by today's standards. I imagine that is what they used, although they could have ordered a limited pressing run, but that would have been incredibly expensive if they didn't need many copies of the discs.

Fascinating links.

Watching someone write a well researched and thought out answer to a, let's face it, sketchy (as well as downvoted) comment is another reason to love HN. :)
