I've heard rumors that some move archival enthusiasts have developed Laserdisc capture hardware which samples RF directly off the laser pickup, for theoretically-ideal capture quality. Anyone know if there's any truth to that, and how to get in touch with such a person if so?

Not only that, capturing the visible video with a capture card doesn't capture the data contained in the vertical blanking region, where many LD arcade titles store data used by the games. Even worse, the digital data stored in some audio tracks can get mangled.
These aren't just theoretical problems, either: M.A.C.H. 3 is only partially playable in MAME, and eventually coughs up an LD error in-game, because the dump has issues with this very data. Being able to create a knowably perfect dump by reading multiple discs would solve this.
