Analog video recording?

For what I know, what counts as 'video' right now is but frames per second, coupled with that effect for which I forgot the name, which gives us the impression of motion. Be it 24 frames/s film, or digital video files on a computer.

Maybe an oversimplification, but isn't this just like sampling (in audio)?

Analog audio, the best form as a vinyl disc, is basically sound engraved physically into a medium and played back as such, have infinite samples.

So is there a technology which will allow video be registered physically (maybe cut onto a disc) thus having an infinite sampling rate, thus having improved video quality (yes I indeed know the Analog vs. Digital debate)?

there is an optical disc that can do analog video

 

it was called laserdisc

 

but as you may already know the video quality of laser disc is somewhere between VHS and DVD and the discs were LP size and required you to flip the disc (unless you had a player that did it automatically) and sometimes even change discs (maximum of 60 minutes per side using CLV and 30 minutes with CAV)

Video on LDs are analog? No wonder LDs have far better picture quality than current DVDs (personal experience).

Film, no, no. 24 frames/s pictures chained together. Basically taking 24 photos per second. Not really video.
