摘要：
A recording medium includes a photosensitive layer, a nonphotosensitive layer, and a recording layer formation region in which the photosensitive layer and the nonphotosensitive layer are laminated. The photosensitive layer includes a recording layer in which interference fringes formed in parallel with a recording medium surface are deleted or changed within a portion irradiated with focused light to record information or light reflected during irradiation of focused light is used to reproduce information.
