Process for manufacturing a record carrier having a cuttable copper layer, wherein a copper layer is precipitated onto a substrate in an electrochemical bath and a desired Vickers hardness in the precipitated copper layer is obtained by controlling the concentration of brightener additives. The copper layer is precipitated in a recrystallizable phase, and the recording is cut while the copper layer is in its recrystallizable phase.
