2 questions

Is there more emf when recording to a DVDR hard drive than from just playing back a prerecorded DVD?

And is there a distance from emf sources at which the emfs are suddenly lower? Thanks.

I don't know about DVDR, although I was burning several around when I really
got ill.

There are near field effects that drop off very quickly, like a couple
inches.. even a fraction of an inch can make a difference.  But there's also
radiation and magnetic coupling that drop off pretty gradually.  If the
circuits are well designed so the currents cancel (no big loops) then it
does drop off pretty fast.  But that's usually not the case (unless it's
high end gear designed to minimize interference... look for coax connectors,
metal chassis, toroidal inductors/transformers...
