MAGNETIC RECORDING MEDIUM |
摘要 |
A magnetic recording medium is disclosed which is produced by applying to a non-magnetic substrate a magnetic coating material containing a ferromagnetic powder and a resinous binder. The coating formed of the magnetic coating material exhibits a deformation ratio (in the direction perpendicular to the film surface from the magnetic layer side) is not more than 1 x 10<-><2> mu m<3>/mgf. This magnetic recording medium possesses a high surface accuracy, retains a highly desirable runnability for a long period of time, and excels in durability. |
