A random access memory with closely spaced ultra-thin continuously rotating flexible magnetic discs is stabilized while being partitioned by an airfoil blade. A shroud member having the form of a section of a cylinder controls air flow within and around the discs under steady state and disturbed conditions. A rigid reference plate controls air flow relative to one end of the disc aggregate. Flexible washer discs having varied diameters, retain the other end of the aggregate and operate as a variable rate spring to damp fluttering movements of the discs caused by operation of the partitioning mechanism. The hollow partitioning blade is adapted to supply slightly pressurized air between an external source and the partition interface. The air is emitted at a critical predetermined angle relative to the interfacing discs and directed at an angle to the entrained air flow within the interface. This serves to stabilize the discs which are not displaced by the blade but which have a tendency to flutter due to the turbulence produced by the partitioning action.
