  • Mechanism for centering and clamping a floppy disc
    Patent number: 4409629
    Abstract: A positioning and clamping system for floppy disc recording media utilizes a tapered positioner cone having extremely pliant petals. The cone defines a nominal circumference which is greater than the disc aperture, and the petals yield to conform to disc placement. Centering is accomplished before clamping by a radial return of the petals to balanced positions, acting against the unclamped disc. The geometry of the cone and follower are such that forces that would tend to distort the cone are minimized.
