Abstract

PURPOSE:To make a titled medium applicable to vertical type magnetic recording with high coercive force and excellent in corrosive resistance, by setting the filling factor of magnetic layer consisting essentially of Co and Cr on a substrate to a specific range. CONSTITUTION:Signals are recorded on a magnetic recording medium 6 provided with a magnetic thin film 7 having easy magnetization axis toward the orthogonal direction of a film on a substrate 1 by a vertical type magnetic head 9 made of a ferromagnetic thin film 8 having an exciting winding 5. In this case, as the magnetic thin film 7 which takes the filling factor X (quotinent of the density of magnetized film divided by the density of a single crystal having the same composition as this magnetized film) as 0.75<=X<=0.95, the thin film consisting essentially of Co and Cr can be used.
