A magnetic transcription device for transcribing information signals of a master information carrier in a magnetic recording medium by applying a magnetic field generated by magnetic field generating means to a contact body obtained by contacting the master information carrier having a base on which ferromagnetic bodies corresponding to the information signals are formed with a magnetic recording medium having a ferromagnetic layer, wherein the magnetic recording medium includes driving means for adjusting a distance between the magnetic field generating means and the contact body while rotating the magnetic field generating means relative to the contact body. Accordingly, an external magnetic field can be applied and removed for transcription of the information signals of the master information carrier in the magnetic recording medium while rotating the magnetic field generating means relative to the contact body, so that the deterioration of reproduction signals from the magnetic recording medium can be prevented.
A magnetic transcription device, for transcribing information signals to a magnetic recording medium having a ferromagnetic layer, the device comprising;
A method for transcribing information signals of a master information carrier to a magnetic recording medium having a ferromagnetic layer, the master information carrier comprising a base and ferromagnetic bodies corresponding to the information signals to be transcribed, the method comprising:
