A method of determining a maximum allowable read power for a drive- record carrier combination is described. The method finds a forward-sense setpoint value to control a light power control loop, by reading data from the record carrier at which degradation of the data occurs. This technique is useful for all optical storage devices such as CD, DVD and Blu-ray players and recorders.
