HEAD USING NEAR-FIELD LIGHT AND INFORMATION RECORDER

摘要

A head using near-field light for recording information by producing near-field light, heating a predetermined region of a medium with the light, and applying a magnetic field to a predetermined region. The head comprises an optical waveguide (103) having a path through which a light beam is propagated and a tip (117) having an optical small opening (118) formed in a position opposed to a predetermined region, and propagating the light beam emerging from the optical waveguide (103) toward the optical small opening (118) while focusing the light beam so as to produce near-field light. The optical small opening (118) is formed of the magnetic poles for applying the magnetic field to the predetermined region.
