ABSTRACT:
A positioning device, comprising a cylindrical guide element and a guide surface, is so designed that an angle of less than 90.degree., especially of from 1.degree. to 80.degree., is formed between an axis at right angles to the direction of movement of the guide element over the guide surface and the axis of rotation of the guide element, in the plane containing these two axes. The peripheral surface of the guide element can be grooved or convex. The novel positioning device can be used with advantage in any type of recording/playback apparatus for disk records.
