To adjust the parameters of a write strategy for recording data on an optical recording medium, the jitter value of a reproduced signal obtained from recorded data is detected. If the jitter value exceeds a prescribed threshold, a write strategy parameter having a comparatively small effect on the jitter value is adjusted, and subsequent data are written on the recording medium using the adjusted parameter. Parameters are selected for adjustment in ascending order of their effect on the jitter value. Stable data recording can thereby be carried out without significant jitter degradation.
