。 A polarizer that polarizes the beam light irradiated from the light source, and an f that passes the beam light deflected from this polarizer.
a θ lens, a first mirror tilted with respect to a plane orthogonal to the optical path passing through the fθ lens near the exit side of the fθ lens; and a reflected light from the first mirror is directed from the deflector to the An optical imaging device characterized by comprising a second mirror that intersects the optical path leading to the fθ lens and reflects the light toward the storage medium.
