Abstract:
1. An optical pickup for recording and/or reproducing with respect to a recording medium, comprising: a light source module in which first and second light sources that emit first and second light beams of different wavelengths are integrated into a single package; an objective lens which focuses the first and second light beams to form a light spot on a recording surface of the recording medium; a light path changer which changes a path along which the first and second light beams propagate; a photodetector which receives the first and second light beams entered via the objective lens and the light path changer; and an optical element which is disposed on the path along which the first and second light beams propagate to act as a lens with respect to only one of the first and second light beams so as to correct a position difference along a light propagation direction between the first and second light sources.
