| 英文摘要 | In case that the light beam emitted from a light source mounted on a base element is focused to a spot litht on a data storage media to write the data, when the light beam reflected from the data storage media to return to the light source is reflected from the base element and focused again on the data storage media, it becomes difficult to precisely read write the data on the storage media. In order to resolve the above problem, a light beam treating means is provided in the base element to prevent the re-incident light beams from being re-I flected toward the data storage media and focused thereon. |
