ABSTRACT:
A method and device for recording signals on a record carrier with the aid of a radiation beam (15). The signals are recorded in the form of optically detectable marks in parallel tracks which have a substantially constant track pitch. The recording intensity of the radiation beam is set in such a way that with a "minimum" recording intensity information patterns are recorded with a low desired error rate "(Block) Error Rate". Furthermore, a method and device are described by which the "minimum" recording intensity of the radiation beam can be determined.
