<P>PROBLEM TO BE SOLVED: To provide a near-field light generating device capable of obtaining near-field light having a stronger light intensity with a simple configuration. <P>SOLUTION: The device includes: a light source 1; a near-field light generating element 5 having a minute aperture having a size not more than the wavelength of light from the light source 1; and an optical system comprising a collimator lens 2, a polarizing element 3 and a condenser lens 4, for converting the light from the light source 1 into circularly polarized light and irradiating the area including the minute aperture of the near-field light generating element 5 with the circularly polarized light. The minute aperture of the near-field light generating element 5 comprises a bent or curved aperture having at least two aperture edges and extended from one aperture edge to the other aperture edge. <P>COPYRIGHT: (C)2007,JPO&INPIT |
