Abstract:
A method for manufacturing an optically readable digital storage disk having an edge contour by the steps of providing a CD-R disk blank having a circular edge and consisting of a plastic disk that is provided, on one side opposite a scanning side, with a reflective layer that lies loosely on the plastic disk, and the reflective layer being connected with the plastic disk along a first line that surrounds an axis of rotation of the storage disk; connecting the reflective layer with the plastic disk along a shaped second line that is closed on itself and that, seen from the axis of rotation, runs outside of the first line, and then cutting the storage disk from the CD-R disk blank along a third line that corresponds to the edge contour, said third line running on the side of the second line that faces away from the axis of rotation.
