Seperate HD & FD controllers?

I've noticed that the 3b1 can only access one disk at a time. I.e., during
floppy disk accesses the hard disk is idle - and vice versa. (Especially
evident during floppy formatting).
However, I've seen references to seperate HD and FD controller chips.
I suspect that there is some common circuitry between the HD and FD interfaces
which prevents them from operating independantly. (IBM PC clones have seperate
controllers which can work independantly - 3b1's don't seem to have that
luxury).
Is this true?
