MASTER INFORMATION CARRIER PROCESS FOR PRODUCING THE CARRIER AND METHOD AND APPARATUS FOR RECORDING MASTER INFORMATION SIGNAL ON MAGNETIC RECORDING MEDIUM BY USING THE CARRIER

摘要

According to the recording method for the magnetic recording medium of the master information signal according to the present invention, the concave-convex shape corresponding to the information signal is formed on the surface of the substrate of the master information carrier, at least a convex part surface of the concave-convex shape is formed of a ferromagnetic material, .; By contacting the surface of the master information carrier and the surface of the ferromagnetic thin film or ferromagnetic powder coating layer is formed of a sheet-like or disk-like magnetic recording medium, and record the magnetization pattern corresponding to the uneven shape of the surface of the magnetic recording medium.
