<p>The warping of the surface of a composite compact disc occurring during the bonding of two surfaces together to form the disc is reduced by the use of a curing filter that modulates the intensity of the ultraviolet light used to set the bonding agent. The curing filter may be in the form of a disc having a greater density near the periphery of the disc than at the center. The disc includes a recorded layer (1), substrate (3), readout surface (5), and reflection coating (7).</p> |
