Patent ID: 8339924

Claim:
An optical pickup device comprising: a first light source for emitting a first light beam having a first wavelength ranging between 390 nm and 420 nm; a first optical system for guiding the first light beam emitted from the first light source to a first optical disc; a second light source for emitting a second light beam having a second wavelength different from the first wavelength; a second optical system for guiding the second light beam emitted from the second light source to a second optical disc different from the first optical disc in regards to recording density; and a light blocking member (i) disposed at a position capable of blocking incident light, of an unwanted light beam having the first wavelength and derived from the first optical system, from entering into an optical component constituting at least a portion of the second optical system but not constituting any portion of the first optical system, and (ii) for blocking the first light beam having the first wavelength, wherein the first optical system includes: a first rise-up mirror for bending the first light beam emitted from the first light source in a direction substantially perpendicular to a recording surface of the first optical disc; and a first objective lens for focusing the first light beam bent by the first rise-up mirror onto the first optical disc, wherein the second optical system includes: a second rise-up mirror for bending the second light beam emitted from the second light source in a direction substantially perpendicular to a recording surface of the second optical disc; and a second objective lens, which is disposed at a position different from the first objective lens, for focusing the second light beam, which proceeds along an optical path different from an optical path along which the first light beam proceeds and which is bent by the second rise-up mirror, onto the second optical disc, wherein the first light source and the second light source are disposed at opposing positions, wherein the first rise-up mirror and the second rise-up mirror are disposed side by side in a direction perpendicular to a radial direction of the first optical disc and the second optical disc, and wherein the light blocking member includes a filter disposed on a surface of the first rise-up mirror which bends the first light beam in the direction substantially perpendicular to the recording surface of the first optical disc, the filter being disposed on at least any area of the surface of the first rise-up mirror on which the first light beam is incident so as to block the first light beam having the first wavelength.
