Abstract: An optical pickup apparatus which includes a light transmitting system is provided. A light source system provides the light transmitting system with light; a light receiving system includes detectors which are configured to detect light reflected from the multilayer optical disk; and a stray light controller is configured to prevent stray light from reaching the detectors. The stray light controller is disposed between the light source system and the light receiving system. The stray light controller includes a light transmitting portion through which light reflected from the multilayer optical disk and the stray light are configured to pass; a light diffraction portion is configured to diffract the light reflected from the multilayer optical disk and the stray light; and a light blocking portion configured to block the light reflected from the multilayer optical disk and the stray light.
