Abstract: A photodetector comprising a photocell assembly including a substrate and at least one photocell formed on the substrate and having a light receiving face. The photocell assembly is completely embedded in a transparent resin molded body which has a light receiving surface to permit incoming light incident thereupon to travel direct to the light receiving face of the photocell. The light receiving surface is roughened, recessed, raised, or inclined. The result is a reduction in the temperature-dependent change in the tracking error signal that normally arises due to light interference.
