MAGNETIC TRANSFER MASTER DISK AND METHOD FOR MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To obtain a magnetic transfer master disk including a magnetic layer and exhibiting excellent shape stability of a protrusion/recess pattern. SOLUTION: An initial layer (16) formed of a conductive film is formed on a surface of a master (26) on which a pattern of minute protrusions/recesses is formed, and then a magnetic layer (principal layer) (14) is formed on the initial layer (16), and then, a metal layer (28) is formed by means of electroforming. A duplicate (30) in which the initial layer (16), the magnetic layer (14) and the metal layer (28) have been integrated is peeled off from the master (26), thereby obtaining the magnetic transfer master disk, which is the duplicate (30) in which the magnetic layer (14) and the initial layer (16) are deposited on the protruded/recessed surface of the metal layer (28).
