from what I can remember reading in the past there is a 
"paramagnetic" effect, when the magnetic data "spots" get too 
small the magnetic field of adjectend "spots" will influence each 
others signal. I do not know if it is like with magnetic tape where 
when wound up the magnetic fields of the sorrounding layers will 
effectively change the magnetic information or if the information 
stays and the fields cannot be interpreted corrctly by the heads.

However I really do not care about capacity, what I want is speed! 
A 4GB drive is enough for me, I want 4 times the speed of a current 
drive. I remember reading about seagate or quantum to experiment 
with some liquids in the drives instead of air to make the positioning 
of the heads faster (and to get the heads closer to the surface to 
get higher densities) but I cannot remember the announcement of 
an actual product or even some results.
