And the spectra laser edit.
The videodisk systems use cav disks with one frame per rotation giving perfect still frames. Only hassle was the cost of glass disk burning as they were single use or 'worm' disks as they we're known at the time (write once read many times). The initial dream was rewritable disks with heating lasers but massive compression met faster disks and it all went pc.
I worked for a while with some guys from paltex makers of the st5 (tempo 76 in NTSC land) and several of them had worked with ediflex and edit droid.
The ediflex was a massive rip off of the cmx 600 by Adrian Ettlinger and Dave Bargen from the early 70s but besides being a proof of concept they only sold about 6 of them as the Winchester disks it used were so expensive. Funnily enough those same disks later formed the backbone of the Quantel Harry but 80 seconds of 422 video wasn't enough to really get many editors excited though I used to cut all the mtv Asia promos in one back in 1991.
Take a look at Timeline two ebooks by John for more about this.

Don't forget the Ediflex. (I had forgotten it.)
