GENERATING METHOD OF NEAR-FIELD LIGHT, MASK FOR NEAR-FIELD EXPOSURE, NEAR-FIELD EXPOSING METHOD AND DEVICE, NEAR FIELD LIGHT HEAD, SCANNING NEAR-FIELD OPTICAL MICROSCOPE, AND RECORDING/REPLAYING DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a method for generating a near-field light which highly efficiently generates the near-field light and also the near-field light having higher intensity, and also to provide a mask for the near-field exposing, the near-field exposing method and device, the nea-field light head, scanning near-field optical microscope, and a recording/replaying device. PSOLUTION: A method for generating a near-field light comprises the steps of: entering a light to microscopic openings having a size of not more than a wavelength of the light; and forming a microscopic light spots in the vicinity of the opening at the light outgoing side of the microscopic opening. In forming the light spots, the microscopic openings are formed in a rectangular shape having vertical and horizontal sizes different from each other to form the light spots having about the same vertical and horizontal sizes with the rectangular-shaped opening.
