PROBLEM TO BE SOLVED: To impart such constitution which can easily make the region width of projecting parts to the light source wavelength at the time of exposure or below in a substrate for the recording medium formed with periodically arrayed rugged shapes on one surface by using a photolithography technique. SOLUTION: The magneto-optical recording medium 1 is constituted by successively laminating a first protective film 3 consisting of a silicon nitride film, for example, a magneto-optical recording film 4 consisting of a Tb-Fe-Co amorphous alloy and a second protective film 5 consisting of a silicon nitride film on a carrier substrate 2 as a substrate for recording media consisting of, for example, an Si substrate. The projecting parts 6 and recessed parts 7 are periodically arranged in a recording track direction (arrow T direction) atop the carrier substrate 2. The region width S1 of the projecting parts 6 is smaller than the wavelength of the light source at the time of exposure and is formed at every other n-times (n is an integer of >=2) of the region width S1 of the projecting parts 6 in the recording trach direction.
