A device in accordance with the invention for recording or reproducing information onto/from a rotating information carrier (10) has rotating element (16) for rotating the information carrier. The device further has conversion (16) for converting a write signal (SW) into a detectable pattern on the information carrier, or for generating a read signal (SLS) in response to a detectable pattern on the information carrier. The device also includes control unit (25, 26) for supplying at least one control signal (SR, SF) to the conversion unit in response to an error signal (RE, FE). The device also includes detection unit (25A, 26A) for generating a detection signal (DR, DF) which is a measure of a periodic variation in the error signal (RE, FE). The device in accordance with the invention is characterized by adjustment unit (29) for influencing the response of the control unit (25, 26) to the error signal (RE, FE) in dependence on the detection signal (DR, DF).
