Summary:To provide a magnetic tape which may contribute to operational stability improvement of a drive during recording and/or reproduction after prolonged storage.SOLUTION: A magnetic tape is provided, comprising a non-magnetic support body and a magnetic layer containing ferromagnetic powder and having a 1-bromonaphthalene contact angle in a range of 45.0° to 55.0°, inclusive, as measured on a surface thereof and a standard deviation σ of the angle of 1.0° or less in a width direction of the surface thereof. Also provided are a magnetic tape cartridge and a magnetic tape device that comprise the magnetic tape.SELECTED DRAWING: None 【課題】長期保管後の記録および／または再生において、ドライブの動作安定性向上に寄与し得る磁気テープを提供すること。【解決手段】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であって、上記磁性層の表面において測定される１－ブロモナフタレンに対する接触角が４５．０°以上５５．０°以下であり、かつ上記磁性層の表面の幅方向における上記接触角の標準偏差σが１．０°以下である磁気テープ。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
