A magnetic recording medium which is uncostly, can dispense with environmental pollution control measures unlike the case of Co or Cr, is highly durable, permits high density recording and comprises a magnetic film selected from the group consisting of: (1) a Fe-N-O magnetic film comprising 70 to 90 atomic % of Fe, 5 to 15 atomic % of N and 5 to 15 atomic % of O, (2) a Fe-C-O magnetic film comprising 60 to 85 atomic % of Fe, 5 to 35 atomic % of C and 5 to 15 atomic % of O, (3) a Fe-P-O magnetic film comprising 70 to 90 atomic % of Fe, 5 to 25 atomic % of P and 5 to 10 atomic % of O, (4) a Fe-Si-O magnetic film comprising 60 to 90 atomic % of Fe, 5 to 30 atomic % of Si and 5 to 10 atomic % of O, (5) a Fe-B-O magnetic film comprising 65 to 90 atomic % of Fe, 5 to 30 atomic % of B and 5 to 10 atomic % of O, and (6) a Fe-Ni-N-O magnetic film comprising 40 to 75 atomic % of Fe, 10 to 30 atomic % of Ni, 10 to 30 atomic % of N and 5 to 10 atomic % of O.
