Current magnetic features are smaller than the wavelength of visible
light,
so the old magnetic fluid techniques won't work on a modern disk (I have
to admit that I could not define "modern" in this sense ... you'd
probably be
fine on an RA60 platter, I've no idea about a mid 1990s 1GB disk
though).
A magnetic force STM is what you want. Knowing this list the next post
will
be someone listing the ones they have on hand :-)
