| 摘要 |
The present invention relates to an apparatus for reading from and/or writing to optical recording media (7) on which data markings (22) are arranged along tracks (20, 20', 20'') arranged next to one another. The apparatus has a light source (1), a focusing means (5) and an intensity distribution converter. The object of the present invention is to propose an apparatus of this type in which both the extent of the focus spot (15) of the primary beam is reduced and the disadvantages occurring due to the secondary beams (16) are reduced. According to the invention, this is achieved by the intensity distribution converter being a filtering strip (14) arranged in the region of the focusing means (5). <IMAGE> |
