Abstract
The invention relates to a recording and/or reproduction apparatus for optical recording media with means for parallel orientation of the scanning device with respect to the surface of the recording medium, the scanning device being arranged on a slide that is guided on a guide rod. A tensioning element is provided, by means of which the guide rod of the scanning device is fixed on a baseplate in order to avoid a force transmission leading to the bending of the guide rod, said force transmission disadvantageously issuing from fixing or adjusting means of the guide rod, in an adjustable manner in a plane corresponding to the cross section of the guide rod. The fixing and adjusting device formed by means of the tensioning element has a small number of individual parts, the guide rod can be mounted on a shaped portion of the baseplate with a low outlay and nevertheless avoids to the greatest possible extent a force transmission to the guide rod that disadvantageously issues from fixing or adjusting means. The fixing an adjusting device is provided in particular for parallel orientation of the scanning device in a recording or reproduction apparatus for optical recording media with respect to the surface of the recording medium.
