Title

(EN) Method and device for determining a set of recording pulse series parameters for optical carrier recording, and optical record carrier

(ZH) 确定用于光载体记录的一组记录脉冲串参数的方法和设备

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.
