    • An optical disk apparatus which records/reproduces data on/from a plurality of types of optical disks. The optical disk apparatus has a plurality of laser diodes. Two laser light rays emanating from two laser diodes are coupled together by means of a coupling prism. The thus-coupled laser light is radiated onto an optical disk. A photodetector is disposed in close proximity to the coupling prism. The coupling prism guides, to the photodetector, a laser light component of at least one laser light ray of the two laser light to be coupled together, the component having not been radiated onto the optical disk on an optical path. Laser light which is not radiated onto the optical disk on the optical path includes diffracted light other than a main beam emanating from the laser diode or laser beam which has not been subjected to coupling at the coupling surface of the coupling prism. When laser light for a CD is caused to pass through the coupling surface and laser light for a DVD is reflected by the same, the CD laser light which is reflected from the coupling surface or the DVD laser light which passes through the coupling surface is guided to the photodetector. The power of a main beam of the laser light is controlled in accordance with the power of the laser light detected by the photodetector.
    • 一种在多种类型的光盘上记录/再现数据的光盘装置。 光盘装置具有多个激光二极管。 从两个激光二极管发出的两个激光束通过耦合棱镜耦合在一起。 将这样耦合的激光照射到光盘上。 光电检测器设置在紧邻耦合棱镜的位置。 耦合棱镜将耦合在一起的两个激光的至少一个激光的激光分量引导到光电检测器,该组件未在光路上辐射到光盘上。 没有辐射到光路上的光盘上的激光包括衍射光,而不是从激光二极管发出的主光束或在耦合棱镜的耦合表面处未耦合的激光束。 当使CD的激光通过耦合表面并且用于DVD的激光被其反射时,从耦合表面反射的CD激光或通过耦合表面的DVD激光被引导 到光电检测器。 根据由光电检测器检测的激光的功率来控制激光的主光束的功率。
