ABSTRACT:
An improved disc memory module design in which mechanical force to shift the data transducers and to rotate the discs is supplied through magnetic couplings to the module, thereby avoiding radial stresses created by mechanical couplings such as belts, splined connection shafts, gears, etc. The use of bearings at each end of the spindle and the head arm shaft also reduces the errors induced by radial stresses on the axis of the head arm shaft and spindle.
