The magneto-optics record system which uses the myopic field optical element

摘要

(57) Abstract It was the magneto-optics record system which uses the myopic field optical element, kurosudo (it crossed of the pair which is approached to record medium very,) the light which connects the tapered (it made tapering,) optical waveguide it possesses to include the read/write head, with of the end and the record medium where the guided wave road makes tapering is given. Length of the guided wave road in order that all lights which enter to the said guided wave road are transmitted to the tapered (it made tapering,) edge, is larger than 1/2 wave length of the light which is transmitted by the guided wave road, in addition, the width is fraction of wave length of light.
