So I don't want to say it's impossible, but I think it would require a lot more creativity.
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 stored entirely analogue. In terms of encoding it’s more similar to a VHS tape than a CD. Kinda crazy.
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.
The sound was also analog to begin with, then the same encoding as CDs, then after that AC-3 and DTS.
And at that point, most players sold were combo players that could also play CDs.
And there was one more disc format: CD Video. It was a CD-sized digital single that also had a LaserDisc section for the (analog) music video. I have a couple; one is Bon Jovi.
