MD register is 43.5 mm. Nikon F register is 46.5 mm. No go no way.
what is register?
So it only affects infinity focus?

As far as I know, no one made a digital camera that could accept Rokkor lenses without an adapter. But despite what you have heard, adapters are not your enemy. I use my Rokkor lenses on Sony digital cameras all the time -- with adapters, of course -- and I've lived to tell about it.
There may or may not be an adapter for your d40, and I have no idea what limitations there will be. You obviously lose auto-focusing, and you'll have to use stop-down metering, but A & M exposure modes will work -- perhaps others. If your camera is APS, the lens focal length will effectively increase.
As Dan posted, the problem is the register or registration distance.
In order to provide the option of using the lens for distant subjects will require you to employ an adapter that would feature one or more lens elements included in the light path - sort of like a teleconverter, but different.
The expense involved, and the quality that results varies among such adapter solutions.
Is this why sometimes when removing lenses from old cameras you find thin shims between the lens and the body?
I think he wants to use them on his Nikon D40, which is a DSLR and has a deeper mount than the minolta, so he wouldn't get infinity focus without additional optics.
Ideally i would like a digital camera that i could use them on with no restrictions or work arounds but if no digital cameras have SR mounts natively then I guess thats moot. I was hoping Konica, or Minolta made digital cameras with SR mount.

Konica Minolta made DSLR but in their A mount not SR mount. They stopped making SR mount cameras sometimes in the mid 80's or so. Minolta changed the mount when they made their AF 35mm SLR.

Make that date closer to 2000 with the late Minolta X-370 variants -- made in China by Seagull. And after Minolta stopped production, Seagull continued to produce dozens of cameras with Minolta SR mounts -- for many years -- some with the same designation: Seagull X-9, Seagull DF-370, etc.

No digital camera has a native SR mount. Almost any mirrorless digital camera with a $9 adapter (which is literally just a metal tube) will work perfectly with all SR mount lenses.
Sony did extend support for A-mount (minolta SLR and DSLRs) by making a series of adapters for their mirrorless alpha series which work very well, and might as well be native support.
how did they overcome the register problem?
There isn't one - the mirrorless Sony FE mount is only 18mm deep, so the adapter needs to add something like 25.5mm to reach the SR mount's depth. The register problem is only with DSLRs which have to be deeper to accommodate the mirror.
