Abstract
(EN)

A method is described for determining a set of recording pulse series parameters for recording information on an optical record carrier. First a series of test patterns is written on the record carrier with a values of the parameters. On reading the test patterns, the jitter values of each read signal is determined. The optimum values of the parameters are derived from a linear dependence between the set of recording pulse series parameters and the relative jitter values. The invention relates also to a device arranged to perform the method. The invention further relates to an optical record carrier comprising the optimum recording power as determined by the method according to the invention.
