I'm reminded of the early IMI "shoebox" drives (shoebox, I guess if you 
had size 21 feet).  I think that they were mostly used by Corvus--clear 
tinted plastic top with a voice-coil positioner.

If you lifted the front end of these things about an inch off 
horizontal, they'd cease to work--the positioner didn't have the moxie 
to overcome the force of gravity and would respond with sort of a 
squealing retry as it tried to push the heads uphill.
