发明名称 MAGNETIC RECORDING MEDIUM AND ITS PRODUCTION
摘要 PROBLEM TO BE SOLVED: To provide a magnetic recording medium with which such required characteristics as output improvement by a head touch, tape interchangeability prevention of occurrence of edge crack by bending rigidity and a decrease of a fluctuation in slit width, are improved by controlling rigidity, thereby enhancing the rigidity particularly in a transverse direction and a process for producing the same. SOLUTION: This magnetic recording medium is constituted by disposing >=1 layer of intermediate layer contg. at least nonmagnetic powder and binder on a base 1 and disposing a magnetic as an upper layer contg. at least ferromagnetic powder and a binder thereon. The nonmagnetic powder of the intermediate layer is acicular and the alignment coefft. (α) of the nonmagnetic powder to its longitudinal direction is 0 to 0.8.
