Abstract
A device includes a casing having a plurality of equispaced openings formed around, and a plurality of spring-loaded radial tongues partially extended out from and retractable into the openings. Each of the radial tongues has a lower curved surface with a constant curvature in any imaginary contour line throughout at least one area of the lower curved surface. Furthermore, the constant curvature is exactly the same as the curvature of the rounded inner edge of the optical disk to be held.
