A method and apparatus for cutting an optical storage disc to a desired shap e, and a method and apparatus for sealing the edge of an optical storage disc, particularly a cut OSD. A die set is disclosed which includes a die plate, punch, and pressure plate . During die. cutting, the OSD is compresses between the punch and the pressure plate, bat h of which correspond to the desired shape. Compression of the OSD during cutting minimizes damage to the data layer of the shaped OSD. Following cutting, sealant is applied t o the edges of the shaped OSD to re-bond the exposed data layer to the OSD and/or to provide a finished edge to the OSD. A system is disclosed for producing shaped OSDs by die-cutting.</SD OAB>
