| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a magnetic tape reduced in total thickness to 4.80 μm or less, the magnetic tape suppressing a reduction in electromagnetic conversion property after repeated running.SOLUTION: There is provided a magnetic tape that has a non-magnetic layer including non-magnetic powder and a binding agent on a non-magnetic support and a magnetic layer including ferromagnetic powder, non-magnetic powder, and a binding agent on the non-magnetic layer, the magnetic tape having a total thickness of 4.80 μm or less and a coefficient of friction of 0.35 or less, the coefficient measured at a base material part on the surface of the magnetic layer.SELECTED DRAWING: None
【課題】総厚４．８０μｍ以下に薄型化された磁気テープであって、繰り返し走行における電磁変換特性の低下が抑制された磁気テープを提供すること。【解決手段】非磁性支持体上に非磁性粉末および結合剤を含む非磁性層を有し、非磁性層上に強磁性粉末、非磁性粉末および結合剤を含む磁性層を有する磁気テープであって、総厚が４．８０μｍ以下であり、かつ、磁性層表面の素地部分において測定される摩擦係数が０．３５以下である磁気テープ。【選択図】なし |
