PROBLEM TO BE SOLVED: To provide a medium manufacturing method, a recording medium and a magnetic disk drive for obtaining high recording density. SOLUTION: A magnetic layer 1 is formed on a substrate 5 (a), and a nano-grain film 16 is formed on the magnetic layer 1 (b). Then, the nano-gain film is used as a mask, the magnetic layer is subjected to cutting (c), the nano-gain film is removed to form artificial fine magnetic grains 2 (d), and an artificial granular magnetic recording medium is obtained.
