MANUFACTURING A DISC-SHAPED PLASTIC RECORD CARRIER |
摘要 |
A method and device for manufacturing a record carrier is disclosed in which a liquid moulding resin is deposited in a cavity formed in the surface of a mould which also has at least one data track. Thereafter a flexible substrate, having a central projection, is deformed into a convex shape and is pressed against the moulding resin. As the projection on the substrate enters the mating cavity in the mold, the resin is squeezed out of the cavity and rolled out across the mould surface by the substrate which is flattened into a planar form during the pressing step. The moulding resin is then cured and the assembly of the substrate with attached, cured resin layer is removed from the mould. |
