发明名称 Magnetic recording medium
摘要 A magnetic recording medium comprises a nonmagnetic support and a magnetic recording layer provided on the support which comprises two layers including a first magnetic recording layer and a second magnetic recording layer. Each of the two magnetic recording layers contains a ferromagnetic powder having a coercive force of not less than 500 Oe dispersed therein. The first magnetic recording layer is provided on the support has a Young's modulus of 500 to 1,000 kg/mm2; and the second magnetic recording layer provided on the first magnetic recording layer has a Young's modulus of not less than 1,300 kg/mm2; and the magnetic recording layers as a whole show a Young's modulus of not less than 900 kg/mm2.
