A beam scanning apparatus includes an optical source, a beam deflector having a deflection disk which is comprised of a plurality of sectors patterned to diffract a beam emitted from the optical source and has a reflective layer for reflecting an incident beam formed on the bottom surface of the beam deflector, and a driving source for rotating the deflection disk. A beam corrector is provided for correcting the beam deflected by the beam deflector.
