Optical pickup and optical disk apparatus

An optical disk apparatus comprising an optical pickup,

• wherein the optical pickup includes:
• a first optical system that collects first laser light emitted from a first laser light source onto a first disk and that receives and guides reflected light from the first disk to a first photoreceptor;
• a second optical system that collects second laser light emitted from a second laser light source onto a second disk and that receives and guides reflected light from the second disk to a second photoreceptor, the second laser light having a wavelength longer than the wavelength-of the first laser light;
• a second objective lens for collecting the second laser light onto the second disk and for receiving the reflected light from the second disk, the second objective lens being movable in a radial direction passing through the center of the second disk;
• and
• a first objective lens for collecting the first laser light onto the first disk and for receiving and guiding the reflected light from the first disk to the first photoreceptor, the first objective lens being disposed offset from the radial direction and adjacently to the second objective lens.
