发明名称 MAGNETIC RECORDING MEDIUM
摘要 PROBLEM TO BE SOLVED: To provide a magnetic recording medium which uses pigment in the lower side layer, which is markedly characterized in that it is every finely pulverized, more economical than the conventional pigment in the lower side layer and magnetically soft. SOLUTION: A multilayered magnetic recording medium, suitable for high recording density and digital recording, having superior electromagnetic recording characteristics and improved surface smoothness and capable of sufficiently absorbing a large quantity of lubricant in the lower side layer, is provided with an upper-side magnetic recording layer, having less than 0.5μm layer thickness and at least one layer of lower side layer which includes the magnetically soft pigment.
