Date Apr. 6, 1995A coated magnetic recording medium includes a nonmagnetic support, a primer layer formed on the nonmagnetic support, and an upper magnetic layer formed on the primer layer. The primer layer and the upper magnetic layer contain, as a binder, a polyurethane resin and a polyvinyl chloride base resin. The weight ratio of the polyurethane resin to the polyvinyl chloride base resin in the primer layer is from 70:30 to 90:10, and the weight ratio of the polyurethane resin to the polyvinyl chloride base resin in the upper magnetic layer is from 20:80 to 40:60. A method for producing the coated magnetic recording medium is also described.
