摘要：
A magnetic recording medium comprises a non-magnetic high-molecular film and at least one magnetic layer containing Co, Ni, Cr and oxygen and formed on the non-magnetic high-molecular film by an oblique incidence vacuum deposition method. The Cr content is within the range of 2 to 8 atom %, the content of oxygen is within the range of 5 to 25 atom %, and the ratio of the number of oxygen atoms to the number of Cr atoms is within the range of 2:1 to 10:1.
