Excuse my ignorance (as always) but could you simply physically scan a laserdisc surface at a microscopic zoom rate, and use a pc to analyze the lans/pits and pull the information from it? That way you could pull a 100% pure video signal from it?
That would most certainly be possible, but very difficult. Consider that the LD itself might be subject to minor warping (many are) and you'd need one hell of a digital tilt servo to compensate for that while tracking.
Then consider that you'd have to contend with occlusion defects (dirt and other material between the plastic and the aluminum layer), possible laser rot (oxidation of the aluminum layer), ..., the list goes on.
And also consider that you'd need access to an electron microscope:
