<P>PROBLEM TO BE SOLVED: To provide an optical disk device for achieving at least one of thinness, reduced size and characteristic deterioration suppression even when corresponding to a laser of various wavelengths including a blue laser. <P>SOLUTION: The optical disk device includes: an integrated element 8; an integrated element 10; a beam splitter 27 for guiding light from the integrated elements 8 and 10 to almost the same optical paths; an objective lens 33; an objective lens 32; and an aberration correction mirror 14 for correcting spherical aberration of the light from the integrated element 8, wherein the light from the integrated element 8 is guided to the objective lens 33 via the beam splitter 27 and the aberration correction mirror 14, and the light from the integrated element 10 is guided to the objective lens 32 via the beam splitter 27. <P>COPYRIGHT: (C)2010,JPO&INPIT |
