ABSTRACT:
A contactless (flying) transducer for scanning a record or recording disc is mounted near the free end of a pivoted arm which is driven in rotation about its pivot by the tangential drive provided by a restrained nut on a threaded motor-driven spindle. A pin extending fron the nut slides without play in a lengthwise groove at the free end of the arm. Rapid operation of the electric motor makes it easy to shift from one part of the record to another and slow movement makes it easy to register precisely with a track. Still finer movement is possible electrically by shifting the transducer on the arm.
