Magnetic transfer method and magnetic transfer device |
摘要 |
A magnetic transfer method which superposes on a magnetic disk surface a magnetic transfer master disk ( 2 ) on which a magnetic film is formed so as to have an array pattern shape corresponding to a preset information signal, and magnetizes the magnetic film on the master disk ( 2 ) to thereby magnetic-transfer-record the array pattern of the information signal on the master disk ( 2 ) onto the magnetic disk as the magnetized pattern of the information signal, the method characterized by comprising a step of contacting/separating to/from a dummy disk ( 1 ) the magnetic film-formed surface of the master disk ( 2 ) to thereby clean the master disk ( 2 ), and a step of superposing, after the cleaning, the master disk ( 2 ) on the magnetic disk for magnetic transfer recording; and a magnetic transfer device for the method.
