The blade thrusts deeply into the pack with distinctively skewed motion gradually and progressively distorting the rotational path of the encountered random segment of discs. Air circulating under slight pressure through passages in the blade into the interface opening formed by the blade operates to suppress fluttering of the discs in the complementary (undeformed) segment.，下面是Aerodynamic partitioning mechanism for random access memory with flexible rotating discs专利的具体信息内容。

权利要求

1. In a random access data storage system, in which a laminar configuration of ultra-thin closely spaced flexible record discs is arranged for continual coaxial rotation as an aerodynamically stabilized unit subject while rotating to being flexibly displaced in a given direction, apparatus for flexing the rotating discs in said given direction at randomly selected lamination interfaces of the aggregate configuration in order to provide stable openings at said interfaces suitable for allowing transducing access to annular interior recording zones of the interfacing disc surfaces, comprising: a blade having an airfoil contour on one side thereof mounted for translational movement parallel to the rotational axis of the discs in a disengaged pOsition relative to said discs and for oblique linear movement relative to the discs at randomly selected lamination interface positions, the latter movement characteristically skewed in said given direction at an oblique angle relative to the undisturbed rotational paths of the discs encountered in and disturbed by such movement; said contoured side of said blade being configured to form a rotationally supportive stable lubricating air film by hydrodynamic action relative to said disturbed discs; said oblique movement being directed at an angle in the range 4* to 11* relative to the undisturbed rotational paths of said encountered discs.

2. Apparatus according to claim 1, wherein the said blade movement is in a chordal path relative to said discs and bends the orbits of said encountered discs along a predetermined chord of their circles of undisturbed revolution.

3. Apparatus according to claim 1 wherein said oblique movement angle is in a critical range of approximately four to eight degrees relative to the undisturbed paths of revolution of the discs.

4. Apparatus according to claim 1 wherein the discs are magnetic oxide coated plastic films approximately 0.0017 inches thick and the unit comprises at least 100 such discs mounted substantially contiguously in said laminar configuration.

5. Apparatus according to claim 1 wherein the discs are vertically oriented, with their common axis of rotation horizontal, and wherein the center of gravity of the encountered discs is below the axis of rotation.

6. Appratus according to claim 5 wherein the blade comprises a hollow closed structure having openings, in a leading edge thereof which intercepts the air carried between the disturbed and undisturbed discs, and having a supply port suitable for conduction of externally pressurized air to said openings via the hollow interior of said structure.

7. Apparatus according to claim 6 wherein said leading edge openings are oriented to direct said pressurized air into the space between separated discs at an oblique angle relative to the encountered discs within a critical range of about 7*-11* relative to the undisturbed paths of rotation of the discs.

8. Apparatus according to claim 2 wherein the camber of the blade contour is continuously varied along the length of the blade to enable said lubricating film of air to form smoothly during the initial encounter of said blade with the encountered discs and thereby reduce the tendency of the interface opening formed by the blade to vary in an unstable mode.

9. Apparatus according to claim 1 wherein the blade has a shape resembling a swept airplane wing.

10. Apparatus according to claim 1 wherein the blade is formed of welded parts surrounding a hollow space, one of said parts having said airfoil contours; said one part and another said part having openings for transferring externally pressurized air through said hollow space to the interface space between discs partitioned by operation of said blade.
