  • Method for the production of multilayer discs
    Patent number: 7335521
    Abstract: A Method for manufacturing an optical disc substrate comprises a first substrate with at least one structured surface, on which an anti-adhesive layer, preferably carbon, is deposited and first layer on top of said anti-adhesive layer. On a second substrate with a structured surface also a layer is deposited. Both substrates are bonded together with the layers facing each other. The separation now easily can take place afterwards alongside the adhesive layer. This way the first layer from the first substrate is being transferred to the second substrate.
