OPTICAL RECORDING APPARATUS AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optical recording apparatus capable of acquiring predetermined resolution even when a line width of an exposure pattern is close to a wavelength of exposed light, and reducing time necessary for exposing, and to provide its method. SOLUTION: An optical recording technique converts light from a light source to modulated light including modulation converted light and phase modulated light to cause the modulated light to form an image on an object to be exposed.
