ABSTRACT:
In a method of manufacturing optically readable discs (1) a substrate (5) is placed on a movable substrate carrier (21) and by moving the substrate carrier it is subsequently placed in a centered position on a previously applied amount of replication material (11) on a mold (15). In this position the substrate is fixed to the mold, after which the substrate carrier releases the substrate and the replication layer in the structure zone (3) is solidified.
