Document Type and Number:
WIPO Patent Application WO/2023/204237
Kind Code:
A1
Abstract:
A magnetic recording medium manufacturing method according to the present invention is a method for manufacturing a magnetic recording medium comprising a substrate, an underlayer, and a perpendicular magnetic layer having an L10 structure in this order, the method comprising a step in which after forming the perpendicular magnetic layer, the surface of the perpendicular magnetic layer is heated with LED light emitted from an LED light source to increase the crystal orientation of the perpendicular magnetic layer, wherein the underlayer contains an NaCl-type compound, and the LED light has a central wavelength of less than 500 nm.
