An electrodynamically controllable pivoting mirror device for an apparatus for optically reading an information carrier with the aid of a beam of radiation, in particular for a video-disc player which utilizes optical reading, the mirror device being provided with a frame on which a mirror, which is mounted with the aid of an elastic plastic, is pivotably disposed, which mirror is pivotable by means of electrodynamic control means consisting of electromagnets and/or control coils. The elastic plastic consists of a rubber-like plastic compound, preferably of a silicone rubber, which is exclusively connected to the underside of the pivoting mirror, the pivoting mirror being supported by a mirror support to which the plastic compound is also connected and which at its side which is nearest the pivoting mirror has a cross-section which is substantially smaller than the surface area of the pivoting mirror and is located at a distance from the pivoting mirror which is less than 3 mm, for example of the order of magnitude of 0.5 mm. In the mirror support a supply duct may be formed which terminates in the end of the mirror support which faces the pivoting mirror. For manufacturing the mirror bearing arrangement, the mirror support and the pivoting mirror are brought into a mutual spatial relationship which substantially corresponds to that of the finished mirror bearing arrangement, after which a plastic compound in viscous condition is applied through the supply duct, the compound being allowed to cure at a later stage.
