Zusammenfassung:A servomechanism for a recording and/or reproducing apparatus using a rotatable recording carrier such as, but not limited to, a rotatable disc on which a video signal is optically recorded, and having a recording and/or reproducing head assembly provided close to or in contact with the carrier, which comprises a servocontrol loop for rendering the positional control to at least a part of the head assembly in response to fluctuations Or the carrier during its revolution which has a gain-frequency characteristic so arranged as to have a plurality of peaks at a frequency corresponding to the revolutions per a second of the carrier and at frequencies of the multiples of the frequency corresponding to the revolutions per a second of the carrier.
