Patent ID: 6859339

Claim:
A master information magnetic recording apparatus comprising, a master information carrier having a surface on which a ferromagnetic thin film pattern corresponding to an information signal is formed, a master information carrier facing member for allowing a recording surface formed on a magnetic recording medium to face the surface of the master information carrier on which the ferromagnetic thin film pattern is formed, and a magnetic field applying member for applying a magnetic field to the ferromagnetic thin film pattern formed on the surface of the master information carrier that faces the recording surface formed on the magnetic recording medium and to the magnetic recording medium in order to record the information signals into the magnetic recording medium, wherein the ferromagnetic thin film pattern formed on the surface of the master information carrier comprises not less than two kinds of different patterns, each having a different pattern angle showing an angle with respect to the direction of the relative movement between the magnetic head mounted on an arm and the rotating magnetic recording medium, and the member for applying a magnetic field applies the magnetic field along the direction which is perpendicular to the direction shown by an angle that is smaller than the maximum pattern angle among the not less than two kinds of patterns, and that is larger than the minimum pattern angle among the not less than two kinds of patterns.
