Information recording/reproduction apparatus

摘要

An information recording/reproduction apparatus including a near field optical head (104) having a minute aperture (206) formed thereon, a substantially rod-like optical waveguide (103) having a core (201) and a clad (202), a reflection surface (203) formed at one of end faces of the optical waveguide, for irradiating light to the near field optical head, a light reception portion and a recording medium, and utilizing near field light, a lens function (205) is formed on a surface of the near field optical head different from the surface of the minute aperture, and a core end face is formed at an intermediate part spaced apart from the reflection surface. <IMAGE>
