摘要：A magnetic transfer method which superposes on a magnetic disk surface a

magnetic pattern from a master disk (), said master disc having on its surface a magneticfilm formed so as to have an array pattern shape corresponding to a preset data signal,magnetized into the magnetic film of the master disk (). The master disc is used tomagnetically transfer the array pattern of the data signal onto the magnetic disk as themagnetized pattern of the data signal. The method characterized comprises steps ofcontacting and separating, to and from a dummy disk () the magnetic film-formed surfaceof the master disk () to thereby clean the master disk (), and a step of superposing, afterthe cleaning, the master disk () on the magnetic disk for effectuating the magnetictransfer.
