In order to ensure recording quality while suppressing the adverse effects due to performance variations among apparatuses and disc radial positions on an optical disc, an optical disc apparatus according to the present invention performs, at the time of data recording, the steps of: acquiring a jitter value and β value from a reproduced signal based on laser light reflected from the optical disc in relation to a disc radial position; learning a β value when the acquired jitter value is a minimum as a target β value; and, if a jitter value acquired thereafter is larger than the minimum jitter value by a preset reference value or above, correcting recording power based on the magnitude relation and the difference between the β value associated with the acquired jitter value and the target β value or performing trial record processing.
