That was a problem with (VHS) video tape, one has to record all the tapes that you want to distribute. That makes it expensive. The pressing or moulding of discs as is done with grammophone records, with CDs and DVDs is the key to success. I can't see that in the videogram. Making one disc that plays is one, but making the next 999 999 discs is something completely different.
Hi Klaas
Yes i think on the videogram it seems a little complex for the market but i suppose a step forward to the 30s 40s audio message recorders they use to have .
Cost wise The Ted and Visc mechanical video records would have been a better idea but i think they just had players no recorders for the public ,the results were similar to VHS beta if they had a recorder would have been interesting to see what happened in the video wars then ....in Australia i can not recall a mechanical record video disc system may be that only played out in the Usa and Europe ?
Not bad quality in the you tube video of the TED system for a floppy record...

In 1978 Matsushita (Technics/Panasonic) re-invented TeD as a 12” rigid LP disc, called Visc. This achieved the apparently impossible, an hour of colour TV on each side. But the groove pitch was 2.3 microns, around 1/25th the pitch for a conventional LP. No pressing plant could have produced the discs.
I found a youtube video of vinylvideo looks perhaps 60 line to me or less...not sure i like there marketing ...but i like the idea of it could be fake send up but what you would expect from a record at that speed .
Arrr this explains it !
