An optical disc device and recording power control method that can ensure the recording quality of data recorded on an optical disc are suggested. When recording data on an optical disc, data recorded on the optical disc is reproduced periodically; a beta value, an index of recording quality of the data on the optical disc, is obtained based on a waveform of the reproduced data; a correction factor of recording power is calculated based on the obtained beta value, and the recording power is corrected according to the correction factor; at the same time, a recording area of the optical disc is divided into a plurality of zones and the correction factor for each zone is managed; and the recording power is corrected according to the correction factor of the zone where data is to be recorded next on the optical disc.
