The levels of leakage fields from scanning are trivial relative to
the field levels required to affect even low-density disks.

The issue with color TVs (and larger color monitors) is the
built-in degaussing coil that goes "THUuummm" when you
turn the set/monitor on to demagnetize the color mask just
behind the face of the tube.

Since the degaussing coil is wound "square" around the
face of the tube, there is substantial demagnetizing field
present at the upper lip of the monitor, where some people
like to put things.
