If the head is off the screw, that's not what's holding it.

They always stick to the hub if not used regularly, and especially if left
sitting in the weeds for a while.
Get the calipers off, and the pads (pitch the pads, as they will have
developed rust between the steel back plate and the friction material, which
will cause the friction mat. to separate)

Spray some of your favorite DE-stick penetrant (PB Blaster?) behind the
disc, all around, where it joins the hub, and around the outer joint with
the hub too, where the hub sticks thru the disc. Also spray some into each
wheel bolt hole along the bolt (it can run down inside between the hub
flange and disc)

Have a beer.

Maybe 2?

Sleep them off.

Take a light hammer and tap all around the disc in an outward direction.
Do not pound violently, or use too much heat, unless you plan to change the
wheelbearing too.

The plan is to crumble the rust holding the disc on, until it starts to move
a little, then wiggle it off rhe hub.  when it moves, or to encourage it to
move,  try driving a thin chisel between the disc and hub flange. (that
could be difficult, as it is recessed), Iv'e never had to do that, but if I
did, I'd drill a hole in the drum the flange is recessed in, to get to the
joint and pry.

Perseverance and cunning beats brute force and ignorance.

Has worked for me, and I did not trash the wheel bearing.
