  • Magnetic tape container
    Patent number: 11842752
    Abstract: The magnetic tape container includes a core around which a magnetic tape is wound. The magnetic tape includes a non-magnetic support, and a magnetic layer including a ferromagnetic powder, and the roundness of the trajectory of one rotation drawn by the magnetic tape in a case where the wound magnetic tape is pulled out from the core is 100 ?m or less as the arithmetic mean of the measured values at three points in the width direction of the magnetic tape.
    Type: Grant
    Filed: February 25, 2022
    Date of Patent: December 12, 2023
    Assignee: FUJIFILM Corporation
    Inventors: Shota Kamimura, Yuto Murata, Tomohide Ueyama, Norihito Kasada
  • Magnetic tape container
    Patent number: 11735219
    Abstract: The magnetic tape container includes a core around which a magnetic tape is wound. The magnetic tape includes a non-magnetic support, and a magnetic layer including a ferromagnetic powder. A maximum value of a deviation of a center position of an average minimum region reference circle of a trajectory of one rotation drawn by the magnetic tape, in a case where the wound magnetic tape is drawn out from the core core is 100 ?m or less for three points of the magnetic tape in a width direction.
