Instead of making the disks go faster (and then having to fill them
with Hydrogen - or run them in vacuum flying the heads magnetically or
electrostatically or whatever to avoid turbulence problems) would it
not be possible to put more than one set of heads on a drive - then
you could reduce rotational delay by only having to wait for the
disk to turn to the nearest set of heads. Has anybody ever tried it,
or does it make the whole drive ridiculously expensive.
