ABSTRACT:
An optical pickup device according to the present invention includes: a first light source that outputs a first laser beam; a second light source that outputs a second laser beam; and an optical system that irradiates an information medium with the first and second laser beams. The information medium includes: an information layer on which user data is written; and a recording layer on which visible information, which is directly visible to a user, is recorded. The optical pickup device is characterized by outputting the first laser beam in writing the user data on the information layer but outputting the second laser beam in recording the visible information on the recording layer.
