An optical disk drive having an optical disk that permits transmission of a laser beam, an optical disk holding mechanism configured to rotatably support the optical disk, a first laser beam irradiation mechanism disposed on one side of the optical disk, causing the first laser beam to be vertically incident on one surface of the optical disk, and a first evanescent optical system disposed on the other side of the optical disk. The first evanescent optical system is configured to receive the first laser beam which emanates from the laser beam irradiation mechanism and passes through the optical disk, and radiate the first evanescent wave to the other surface of the optical disk having at least one recording surface.
