ABSTRACT:
A magneto-optic recording system employing near-field optics which includes a read/write head having a stylus comprising a pair of crossed tapered prisms made of a material having a high index of refraction closely adjacent to the recording medium to provide light coupling between slits at the ends of the prisms and the recording medium. The length of the prism slits being greater than one-half the effective wavelength inside the material filling the prism of the light transmitted by the prisms to transmit all light entering the waveguide to the tapered end and the width being a fraction of a wavelength of the light.
