An optical disc recording/reproducing apparatus is provided which can obtain the best recording quality. Data is recorded while tracking is displaced by gradually supplying an offset voltage (deviation value) to a tracking error signal, and then reproduction is performed on a recording area. The jitter value (reading state of address information) of biphase data generated from a reproduction RF signal is detected by a biphase jitter detector ( 20 ). Further, on the basis of the offset voltage value (tracking deviation) supplied to the tracking error signal and the detected jitter value of the biphase data, a CPU ( 14 ) determines an offset voltage value where the biphase data has the minimum jitter value, as a tracking deviation for obtaining the best reading state of data, and records the offset voltage value in memory ( 15 ).
