ABSTRACT:
An optical head device includes a base member having an attachment surface passing a laser beam of light reflected by an optical disk, a block in the form of a wedge having an attachment surface adjacent to that of the base member and an attachment surface opposite that adjacent to the base member's attachment surface, and a photodetector arranged on the block's attachment surface opposite that adjacent to the base member's attachment surface to receive a laser beam of light having passed through the base member's attachment surface. The block's attachment surface opposite that adjacent to the base member's attachment surface inclines relative to the base member's attachment surface. The optical head device further includes adhesive fixing the block on the base member's attachment surface at a desired position and adhesive fixing the photodetector on the block's attachment surface opposite that adjacent to the base member's attachment surface at a desired position.
