Summary:Provided is a magnetic tape which includes a non-magnetic support and a magnetic layer containing ferromagnetic powder. In this invention, the non-magnetic support is a polyethylene naphthalate support having a Young's modulus of 10,000 MPa or higher in the width direction thereof. The rate of change in friction coefficient against an LTO8 head before and after storage as measured on the surface of the magnetic layer is 0.7 or higher. L'invention fournit une bande magnétique qui possède un support non magnétique, et une couche magnétique contenant une poudre ferromagnétique. Ledit support non magnétique consiste en un support de naphtalate de polyéthylène dont le module de Young dans la direction largeur est supérieur ou égal à 10000MPa. Le taux de variation avant et après stockage du coefficient de friction d'une paire de têtes LTO8 mesuré pour la surface de ladite couche magnétique, est supérieur ou égal à 0,7. 非磁性支持体と強磁性粉末を含む磁性層とを有する磁気テープが提供される。上記非磁性支持体は幅方向のヤング率が10000MPa以上のポリエチレンナフタレート支持体である。上記磁性層の表面について測定される対LTO8ヘッド摩擦係数の保存前後の変化率は0.7以上である。
