Optical head device and adjusting method therefor

An optical head device for use with an optical disk comprising:

• at least one laser beam emitting element;
• an objective lens for converging a laser beam which is emitted from the laser beam emitting element to an optical disk;
• a light receiving element which is provided with a light receiving face for receiving a reflected light from an optical disk, the light receiving face being disposed to face an incident direction of the reflected light to the objective lens;
• a beam guide mirror for guiding the reflected light to the light receiving face;
• and
• a main body frame on which at least the light receiving element and the beam guide mirror are mounted;
• wherein one of the light receiving element and the beam guide mirror is disposed such that its mounting position is adjustable in parallel with the light receiving face and in two dimensional directions, and
• the other of the light receiving element and the beam guide mirror is disposed such that its mounting position is adjustable in parallel with the light receiving face and in one dimensional direction.
