ABSTRACT:
An optical device and an information recording/reproducing apparatus using the optical device are disclosed. Incident light is output to a path selected from a plurality of paths so that an optical path can be secured with high precision for a separated (two-part) optical system. The optical device and the information recording/reproducing apparatus include a first reflective unit for reflecting the incident light in a fixed direction, and a second reflective unit for reflecting the light received from the first reflective unit to a second optical path. The two reflective units are movable in a body between two positions, one position being on a first optical path, and the other position being in an evacuation position where the first optical path is not intercepted.
