Abstract
A method for manufacturing a magnetic domain wall displacement type magneto-optical medium includes forming a magnetic layer on a substrate and forming sectioning regions in which perpendicular magnetic anisotropy of the magnetic layer is reduced, and a plurality of belt-shaped recording tracks are sandwiched by the sectioning regions and are magnetically separated from each other by irradiating the magnetic layer on the substrate with a light beam or a charged particle beam of a wavelength of not more than 550 nm and scanning the light on the substrate in parallel and at a same interval and a magnetic domain wall displacement type magneto-optical medium.
