Now I wonder if something similar is possible with the magnetic fields on VHS tape
So I don't want to say it's impossible, but I think it would require a lot more creativity.
Fun fact about laser discs. They are analogue not digital. CD’s store digital information with the presence or absence of pits. Fairly ancient but still fundamentally feels like a very old version of a thumb drive. Laser discs are not digital. They encode the analogue video signal’s value as the length of the pit. It is digitized in the time domain - sampled at some frequency, but the “vertical” signal value is store…
Laser disks are 100% digital (as you said, they store digits in the time domain).
They don't encode their data using binary like a CD does.
"Binary" and "digital" are two separate and unrelated concepts.
Is there a version that doesn't require watching a video please? This would be 10x faster and easier as a text blob
Earlier quoted context omitted.
Only the CD had uncompressed data.
CED, not CD. And LDs most definitely also have uncompressed data, resulting in visible text at 22:30 in the video.

The sound was also analog to begin with, then the same encoding as CDs, then after that AC-3 and DTS.

It's likely based on just the transcript, even if it describes visual things, it likely guesses those things from the transcript text only. Maybe it's better now, but that was how it did it recently. To be convinced that it "watches" the video, I would need to see evidence of it referring to facts that are strictly only possible to know from the video, but not guessable from the audio.
Each revolution is one frame, so if you compare the data paths next to each other, they don't make up an image but the same single line of several consecutive frames.
Scrolling a still image makes the same line on the screen cover a different part of the image each frame, so you can sort of make out what the original image looked like.
The end credits should show up as a single tall image, since the only limit to the height is the radius of the disc.

Long answer: Just jump around. Once you get to the last 1/3rd of the video, there's a lot of close ups of the part of the laserdisc that recorded the credit sequence. The on-screen (laserdisc) text is clearly visible.
The author moves a flashlight around to show how the angle is important; something that won't come across as well in a blog entry.

If you watch the video, he looked at both.
Yes, but the end credits mentioned by the parent and the link to the image is the CED. That and the title of this post make it seem like this level of image clarity is from a LaserDisc which its not. I think it's worth being clear.
