For achieving an improvement on recording/reproducing quality of information, with enabling more adequate tilt adjustment, even for an optical disc to be used under a circumstance having a large temperature change, an optical disc apparatus for conducting recording or reproducing of video information onto/from the optical disc 2, through buffers 17 and 18, while conducting a tilt adjustment through a learning of a tilt amount, comprises a temperature sensor 4 for detecting temperature within an optical pickup 1, wherein a control unit determines whether a relearning of the tilt amount of the optical pickup, upon basis of a change of temperature detected, a movement amount of the optical pickup between the time when a previous learning is done and the time when a present learning is done, and a remaining memory capacity of the buffers.
