ABSTRACT:
A transducer feeding mechanism in an apparatus for recording and reproducing a signal on and from a rotary recording medium by means of a transducer fed over the recording medium in the radial direction thereof comprises a rotational motive power source having a rotary shaft and a pinion provided on the shaft, a rack meshed with said pinion and fed in translational movement by the rotation of the pinion, at least two guide bars extending parallelly in the direction of feeding of the transducer, a first feeding carriage on which the rack is mounted and which is guided by one of the guide bars, biasing means provided on the first feeding carriage and functioning to contact another guide bar in an elastic manner and to urge the first feeding carriage in a direction to cause the rack to mesh further with the pinion, a second feeding carriage on which the transducer is mounted, and which is guided by said other guide bar, a guide member mounted on the second feeding carriage and contacting in a rotationally displaceable manner said one of the guide bars, and engagement means functioning to place the first and second feeding carriages in contacting engagement in the feeding direction along the guide bars and in a mutually displaceable state within a plane perpendicular to the feeding direction.
