A method for manufacturing optical information carriers, in which a photoresist layer (20) on a master disc (5) is exposed by a radiation beam (19). The intensity of the radiation beam is controlled by a modulator (14) and a control device (10) in such a manner that the exposure dose has a constant predetermined value over the length of a recorded area, which value is independent of the length of the area.
