发明名称 MAGNETISCH REGISTREERMEDIUM.
摘要 A magnetic recording medium comprises a first magnetic layer containing magnetite or a cobalt doped magnetite which is coated on a non-magnetic substrate; and a second magnetic layer coating a cobalt doped gamma -Fe2O3 which is coated on said first magnetic layer. The magnetic recording medium has a high recording sensitivity, a high dynamic range, a less output fluctuation and especially superior sensitivity in low frequency band and superior maximum output level without a deterioration of transfer characteristics.
