ABSTRACT:
A magneto-optic recording system employing near-field optics which includes a read/write head having a pair of crossed tapered optical waveguides closely adjacent to the recording medium to provide light coupling between the tapered ends of the waveguides and the recording medium. The length of the waveguides being greater than one-half the wavelength of the light transmitted by the waveguides to transmit all light entering the waveguide to the tapered end and the width being a fraction of a wavelength of the light.
