Abstract:
A conformal disk holder for holding a rotating disk against a surface comprising:a holder cover of circular shape having a first diameter, a center aperture for accessing a center flexural plate, and a means for connecting a rotating shaft; a center flexural plate of circular shape having a second diameter smaller than said first diameter for fitting inside a downwardly protruded edge portion on said holder cover; said center flexural plate being equipped with a center protrusion having a downwardly facing convex surface and at least three notch openings equally spaced-apart along a peripheral edge of the plate; and a holder base of circular shape having said first diameter and a center protrusion with an upwardly facing concave surface adapted for intimately engaging said convex surface on said center flexural plate so as to allow at least a 5Â° tilt of the holder base from a horizontal plane, said holder base further comprising at least three locating pins extending upwardly from a top surface of said holder base adapted for engaging said at least three notch openings in said center flexural plate, and means for fastening a disk onto a bottom surface of the holder base.
