Abstract:
A method for manufacturing a magneto-optical medium in which a domain wall of a recording magnetic domain is displaced in accordance with a temperature distribution in the magneto-optical medium comprising, in order:(a) the step of forming a magnetic layer on a substrate; (b) the step of forming on the magnetic layer a dielectric layer; (c) the step of forming sectioning regions in which perpendicular magnetic anisotropy of the magnetic layer is reduced by irradiating the magnetic layer on the substrate with a light beam of a wavelength of not more than 550 nm or a charged particle beam through the dielectric layer from a side opposite a side of the magnetic layer facing the substrate surface and scanning the light beam or the charged particle beam on the substrate in parallel and at a same interval, thereby magnetically separating from each other a plurality of recording tracks sandwiched between said sectioning regions; and (d) the step of forming on the dielectric layer a protection coat.
