A recording and/or reproduction apparatus of an optical disc having recording tracks in which mirror areas are formed incorporates an optical head for recording or reproducing information signal onto or from the optical disc which has an optical detector for detecting a tracking error signal by a push-pull method; a fine actuator for precisely actuating the optical head finely; detecting means for detecting an output signal of the optical detector responding to reflected light from the mirror area; and driving means for driving the fine actuator in response to an output signal of the detecting means during the seeking operation.
