摘要： In an optical beam transmissive adjusting mechanism (110) included in an optical pickup device, arrangement positions of a first transmissive element (111) having a first transmittance and a second transmissive element (112) having a second transmittance higher than the first transmittance are switched by a rotational drive unit (105), and an optical beam having a first optical power and an optical beam having a second optical power are output selectively. Furthermore, since a transmissive element of a non-transmissive side for an optical beam is arranged at an angle inclined to an optical axis of the optical beam, the transmissive element does not obstruct a path of the optical beam to be diffused.
