| description | To provide a magnetic tape that is excellent in running stability when recording and/or reproducing data with a dimension in a width direction of the magnetic tape controlled by adjusting a tension to be applied in a longitudinal direction of the magnetic tape.SOLUTION: One embodiment of the present invention is a magnetic tape in which a differential (S0.1-S1.6) between spacing S0.1 obtained after n-hexane cleaning in a surface of a magnetic layer and spacing S1.6 thereto is equal to or less than 32 nm. S0.1 is a value obtained as the spacing under pressing force of 0.1 atm from a relational expression between pressure and spacing obtained through spacing measurements by respective optical interference methods under pressing force of a plurality of different pressure after the n-hexane cleaning in the surface of the magnetic layer, and S1.6 is the spacing measured by the optical interference method under pressing force of 1.6 atm after the n-hexane cleaning in the surface of the magnetic layer. One embodiment of the present invention is a magnetic tape cartridge and a magnetic tape device that include the magnetic tape.SELECTED DRAWING: None
【課題】磁気テープの長手方向にかかるテンションを調整することによって磁気テープの幅方向の寸法を制御して記録および／または再生を行う際の走行安定性に優れる磁気テープの提供。【解決手段】磁性層の表面においてｎ－ヘキサン洗浄後に求められるスペーシングＳ０．１とスペーシングＳ１．６との差分（Ｓ０．１－Ｓ１．６）は３２ｎｍ以下である磁気テープ。Ｓ０．１は磁性層の表面においてｎ－ヘキサン洗浄後に複数の異なる圧力の押圧下でそれぞれ光干渉法によってスペーシング測定を行い得られた圧力とスペーシングとの関係式から０．１ａｔｍの押圧下でのスペーシングとして求められた値、Ｓ１．６は磁性層の表面においてｎ－ヘキサン洗浄後に１．６ａｔｍの押圧下で光干渉法によって測定されたスペーシングである。この磁気テープを含む磁気テープカートリッジおよび磁気テープ装置。【選択図】なし |
