may i ask...why? floppy is dead.
long live flash and specially serial versions like SD...
are you looking just for pinout (easy to find on web) or addressing?
check wiki for details (and the reference links)
i will the other way round , storing it in sd card will more viable (non volatile,no fungus,higher storage,small size, faster read/write, solid state design etc..).
Floppy isn't practical, it's requirements are too great for a micro-controller, forget that idea and use flash memory cards (of some type), there are plenty of examples on the net.
