ABSTRACT:
Optical shutters having a magneto-optical material confined in a holding plate which allows a light to pass through the magneto-optical material. When the intensity of a magnetic field applied to the magneto-optical material is changed, an amount of a polarized light passing through the magneto-optical material is adjusted. A magnetic head with a coil has open ends which are disposed to face the outer surface of a shutter member. A plurality of such optical shutters are arranged to form an optical shutter array.
