Basically splits the disk into two parts: upper & lower. Each part has the
heads which reference it on separate actuators so the they can be on
different cylinders.
Whoever said, "Currently, operating systems read and write data to a
single disk drive" is clearly out of touch. Any number of operating
systems support more than one, including Windows. Then there are things
like DS8Ks and SANs with arrays of more than one physical drive per
logical volume.
That said, it's interesting. I have to wonder whether load-leveling
within and among arrays is more or less effective than this or whether
the two will be someday combined.
