Abstract:
A master information magnetic recording apparatus for magnetically recording a master information signal into a ferromagnetic layer of a magnetic record medium by using a master information carrier comprising a substrate, a first area provided on the substrate where an embossed pattern composed of a ferromagnetic film and corresponding to the information signal is formed on the surface of the substrate, and a second area provided on the substrate where the embossed pattern is not formed, the apparatus comprising:contact means for putting the magnetic record medium into close contact with the master information carrier; positioning means for positioning the magnetic record medium and the master information carrier with respect to each other; and magnetic field applying means for applying a magnetic field to excite the ferromagnetic film of the master information carrier; wherein the master information carrier has through holes at least partially in the second area, and the contact means comprise a suction mechanism for sucking out air between the magnetic record medium and the master information carrier through the through holes in the master information carrier while the master information carrier is in contact with the magnetic record medium, so as to ensure secure contact between the magnetic record medium and the embossed pattern of the master information carrier.
