ABSTRACT:
In the disclosed apparatus, a slide is mounted on a guide bar for longitudinal as well as rotary motion. A recording instrument projects from the slide and a spring biases the slide about the guide bar so as to press the recording instrument against the record carrier. The speed measuring device moves the slide longitudinally on the basis of the measured speed.
