| 英文摘要 | [PROBLEMS] To provide an optical pickup device and recording/reproduction device capable of rapidly and smoothly performing power setting of recording laser light for a recording medium of 2-photon recording type. [MEANS FOR SOLVING PROBLEMS] Recording light and reproduction light emitted from a fetom second laser (111) and a semiconductor laser (112) respectively are converged onto a target recording layer (15) by a recording/reproduction objective lens (118). Among the reflected light from the target recording layer (15), only the reproduction light is introduced to an APD (121) by a polarization beam splitter (115) of wavelength selection type. Accordingly, during recording, by monitoring a signal outputted from the APD (121), it is possible to judge whether the recording state form the target recording layer (15) appropriate. According to the judgment result, power of the recording light can be controlled. |
