PURPOSE:To obtain a magnetic recording medium superior in electromagnetic characteristic and durability, by forming a resin coating film, which has recesses due to elution of needle-shaped inorganic matters, on a base and vapor-depositing a ferromagnetic metal onto this film from the oblique direction to form a magnetic film. CONSTITUTION:A resin coating film 2 which has recesses 3 due to elution of needle-shaped or flake-shaped inorganic matters is formed on a base 1, and a ferromagnetic metal or alloy is vapor-deposited in vacuum onto this film 2 from the oblique direction (for example, the direction of an angle alpha of incidence 70 deg.) to form a magnetic film 4. The magnetic film 4 has >=100Angstrom width in the recording direction and has >=3 partitions, which buffer the magnetic mutual function, within 10mu length. Iron oxide red, goethite, gamma-Fe2O3, or the like is used as said inorganic matters. |
