| 英文摘要 | An optical pickup which can be employed for different formats of a disk recording medium is disclosed. The optical pickup device includes a light source (30) including first (41) and second (51) vertical cavity surface emitting lasers closely disposed to each other for emitting light having different wavelengths and different radiation angles, an objective lens (65) for focusing the light emitted from the light source (30) on a recording surface of a recording medium (10), a photodetector (67) for detecting information signals and error signals by receiving the light reflected from the recording medium (10), a polarized beam splitter (61) disposed on an optical path between the light source (30) and the objective lens (65) to redirect a proceeding path of incident light, and a wavelength plate (63) disposed on the optical path between the objective lens (65) and the polarized beam splitter (61) to convert a polarization component of incident light. |
