Optical pickup device

An optical pickup device for recording information onto and/or reading out information from an optical recording medium, comprising:

• a light beam source for generating a light beam to be projected toward the optical recording medium;
• a light beam detector for receiving the light beam reflected by the optical recording medium so that the information is read out from the light beam after reflected by the optical recording medium;
• a container housing therein the light beam source, and including an aperture through which the light beam generated by the light beam source proceeds toward the optical recording medium;
• a light beam guide member mounted on an outer surface of the container and covering the aperture to guide the light beam after reflected by the optical recording medium toward the light beam detector;
• and
• another light beam guide member for guiding the light beam generated by the light beam source toward the optical recording medium, wherein
• the another light beam guide member is housed in the container.

• another light beam source for generating another light beam to be projected toward the optical recording medium;
• and
• another light beam guide member housed in the container to guide at least one of the light beam and the another light beam before proceeding into the light beam guide member so that a direction in which the light beam proceeds into the light beam guide member toward the optical recording medium is substantially parallel to a direction in which the another light beam proceeds into the light beam guide member toward the optical recording medium, wherein
• the light beam source and the another light beam source are housed in the container, and
• a direction in which the light beam proceeds out of the light beam source toward the optical recording medium is prevented from being substantially parallel to a direction in which the another light beam proceeds out of the another light beam source toward the optical recording medium.
