Zusammenfassung:	PURPOSE:To provide a magnetic recording medium excellent in crystal orientation property and capable of ensuring a satisfactory amorphous surface excellent in surface smoothness, to extremely reduce the floating extent of a magnetic head and to attain high S/N even at >=1 gigabit/in surface recording density. CONSTITUTION:A perpendicular two-layered film medium or an intrasurface thin film medium with hexagonal magnetic alloy films 3, 3 as information recording layers on a thermally oxidized Si single crystal substrate 1 is used. In the case of the perpendicular two-layered film medium, recording is carried out with a single magnetic pole head and reproduction is carried out with a magneto-resistance effect type head. In the case of the intrasurface thin film medium, recording is carried out with an inductive thin film head and reproduction is carried out with a magento-resistance effect type head.
