Abstract

In a file of multiple floppy type discs 1, rotating about a common axis 2, the possibility of friction between the discs and stationary stabilizer plate 3 is eliminated, by the interposition of a rotating stabilizer member 4 between the discs 1 and the stationary plate 3. The central portion of stabilizer 4 is a flexible metal diaphragm 5 and the outer annular portion is a flat and parallel rigid material, for instance, aluminum.

Frictionless Disc Stabilizer

In a file of multiple floppy type discs 1, rotating about a common axis 2, the possibility of friction between the discs and stationary stabilizer plate 3 is eliminated, by the interposition of a rotating stabilizer member 4 between the discs 1 and the stationary plate 3. The central portion of stabilizer 4 is a flexible metal diaphragm 5 and the outer annular portion is a flat and parallel rigid material, for instance, aluminum.

When the discs 1 are separated for transducing access, or when a head force is applied to the discs, the outer portion of the interposed stabilizer 4 provides air-backed cushioning relative to the stationary plate 3. Three equally spaced air bearing ports located in the stationary plate 3 maintain true running of the rotating stabilizer 4.
