| titleOfInvention | Method of and apparatus for manufacturing a disc- shaped plastics record carrier |
| abstract | PHN. 9523 12 ABSTRACT: In a method of manufacturing a disc-shaped plastics record carrier having a laminated structure, a quantity of moulding resin in liquid form is deposited in a central cavity in a mould surface which is formed with an information track or tracks of spiral or circular form. A flexible plastics substrate which has a central boss with shape complementary to that of the cavity in the mould surface, and which has been deflected into a spherosymmetrically domed shape with its convex side facing the moulding resin, is then pressed against the resin and flattened so that the resin is rolled out over the mould surface. The moulding resin is subsequently cured and the assembly thereto is removed from the mould. By initially depositing the moulding resin in a central cavity in the mould surface, the formation of air bubbles in the resin due to the resin being pulled towards the approaching substrate by static electricity in the substrate is inhibited. In an alternative embodiment the liquid mould-ing resin is initially deposited in a central cavity in a rigidly supported plastics substrate, and a flexible mould plate having a mould surface which is formed with the information track or tracks and with a central boss is deflected into a spherosymmetrically domed shape and pressed against the moulding resin. |
