An optical pickup device compatible with two types of optical recording
media in accordance with the present invention includes: a first light
source emitting a first laser beam with a first wavelength; a second
light source emitting a second laser beam with a second wavelength
greater than the first wavelength; an objective lens with parameters
according with the first wavelength and adapted to focus the first and
second laser beams on the at least two types of optical recording media;
a collimating lens for collimating an incident beam of light and
transmitting the collimated light beam to the objective lens; an optical
path synthesizer/separator for receiving the first and second laser beams
and transmitting the first and second laser beams to the collimating
lens; and a compensator for correcting the second laser beams and
transmitting the corrected second laser beams to the optical path
synthesizer/separator.
