that can be a problem because of standard form factor. It'll bad if you super disc wouldn't fit in any case.

Sperry made a disc drives ? I know only few peaceful products from them like bomb ranging system (UK and US bombers in WWII), ranging system for cruise missiles and ICBMs.
... and of course tons of aviation equipment like speedometers, artificial horizons and altitude meters (in unlucky cases also fathometer).

Already done, if you use a screwdriver, you'll find that drive in your PC has up to 2 disc (Seagate terminology) and up to 4 reading heads (for 60+ maybe 80+ GB HDD depending on producer).
