MAGNETIC RECORDING MATERIAL, ITS USING METHOD AND ITS PRODUCTION

PROBLEM TO BE SOLVED: To provide a magnetic recording material improved in the surface shape, having a good traveling property, particularly an improved output level, a low modulation noise and a less fluctuation in the output level during traveling of a tape. SOLUTION: This recording material consists of a nonmagnetic substrate and more than one different layer provided on this substrate and at least one layer among these different layers is a magnetic layer suitable for storing information. In this case, when the recording material 3 is mounted on a reference surface 2 while a surface 3' opposite to an information recording head imparts the tension of about 14-200 mN to the recording material 3, the recording material 3 has such a surface shape that 50% of the surface 3' is separated from the reference surface 2 by
