Since one of the problems with a fast optical disk is the movement of
a heavy arm and head mech. would be to not move the arm but to move
the data.  Yes I know the disk spins, but magnoptical disk use
magnetic domains.  One form of magnetic domain is a bubble memory. 
The next step beyound bubble is Block wall magnetic domains, where
the bubble is made long and skinny, and the wall of the bubble 
is used to contain a 0/1 value.  Thus you could just route this 
long skinny bubble around under the head and use the lazer to
read/write on the bubble wall.
