A method and an optical recording apparatus for determining the optimum write power in an OPC-procedure are described. The method involves erasing a test area, recording test patterns in the test area, reading the recorded test patterns and determining the optimum write power from signal portions of the read signal. Erasing the test area, even when no signals are recorded therein, produces a reliable and unambiguous value of the optimum write power. |
