Document Type and Number:
WIPO Patent Application WO/2011/132747
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing, at low temperature, a magnetic recording medium provided with an L10FePt thin film having high L10 order and excellent orientation properties. Further disclosed is a magnetic recording medium which is provided with an L10FePt thin film and which has been obtained by means of the method. The disclosed production method is for a magnetic recording medium (10) wherein a magnetic recording layer (2') is formed, said layer containing an FePt alloy having an L10 order structure and a metal oxide, and includes a thin film formation step (S1) wherein a thin film (2) is formed, said film containing an FePt alloy and a metal oxide having a melting point of 100˚C-500◦C; and a heating step (S2) wherein the thin film (2) is heated to a specified temperature. Also disclosed is a magnetic recording medium (10) obtained by means of said method.
