The present invention is directed to a recording and reproducing apparatus in which a tracking error between a recording head and a reproducing head secured on a rotary actuator is canceled to thereby effect an accurate tracking. A recording and reproducing apparatus in which a recording head and a reproducing head are secured on a rotary actuator with a constant distance therebetween comprises a rotation angle detector (3) for detecting a rotation angle of the rotary actuator (1) and a servo correction amount generator (4) for generating a servo offset amount corresponding to the change of the rotation angle of the rotary actuator (4), wherein a servo offset based on the servo offset amount from the servo correction amount generator (4) is supplied to the rotary actuator (1) in such a fashion that at least in one of recording and reproducing modes a tracking error between the recording mode and the reproducing mode which takes place due to a distance between the recording head and the reproducing head and due to the rotation angle of the rotary actuator (1) is canceled.
