ABSTRACT:
Discloses a system for stabilizing thin flexible foil recording discs (such as TV recordings) against axial fluctuation when rotated at high speeds (1500-5000 rpm). May include stationary guide plates formed and disposed to confine the rotating disc in such manner that the rotating disc pumps a uniform, radially moving and stabilizing layer of air outwardly between the rotating disc and each guide plate. May also include windows to optically scan the recording disc, as needed. Discloses alternate kinds of suitable recording discs.
