| 摘要 |
The present invention relates to a device for reading from and/or writing to optical recording media, having a light source for producing a scanning beam for scanning the optical recording medium, detection means for detecting the beam influenced by the optical recording medium, and an optical element arranged in the optical beam path by means of a holder. The optical element has in a plane perpendicular to the axis of the beam path outer boundary lines inclined to one another in such a way as to enable a unique orientation. The holder has a cutout with correspondingly inclined inner boundary lines.
