The upper head -- the one that points down -- is side
1. Side 0 is the
underside of the disk. The way to rememebr that is that the single-head
drive has the lower head only with a preasure pad on the moveable part of
the arm. And yes, single-head 3.5" drives do exist (as for that matter to
40 cylinder ones -- 67.5 tpi)/
They are very common on european MSX machines. And most of them has
drive belts! :oO
