A transducer feeding mechanism is used for 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. The mechanism 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, a single guide bar extending in the direction of feeding of the transducer, a first feeding carriage on which the rack is mounted, and which is guided by said guide bar, a second feeding carriage on which the transducer is mounted, and which is guided by said guide bar, a contact bar extending in substantially parallel with the guide bar, a contact member mounted on the second feeding carriage and contacting said contact bar, and biasing means provided between the first and second feeding carriages and functioning to impart torques to the first feeding carriage in a direction to cause the rack to mesh further with the pinion and to the second feeding carriage in a direction to cause the contact member to contact the contact bar.
