Patent ID: 7301864

Claim:
An optical pickup device comprising: a first optical unit, emitting a first wavelength of light; a second optical unit, emitting at least one or more of wavelengths of light longer than the first wavelength; a light-receiving member, receiving a light reflected from an optical disk; a correcting member, correcting for spherical aberration of the first wavelength of light; an optical member, guiding the first wavelength of light and the wavelength of light longer than the first wavelength to substantially a same optical path; and a focusing member, focusing a light from the optical member, wherein the first wavelength of light emitted from the first optical unit is passed through the correcting member and the optical member, and then focused by the focusing member and illuminated onto the optical disk while the first wavelength of light reflected upon the optical disk is passed through the focusing member, the optical member and the correcting member, and then entered into the light-receiving element.
