TAPE, TAPE CARTRIDGE, AND TAPE DEVICE

The present invention addresses the problem of providing a magnetic tape in which there is little deterioration in electromagnetic conversion characteristics even if the magnetic tape travels repeatedly. A magnetic tape having a non-magnetic support and a magnetic layer containing a ferromagnetic powder. The magnetic tape contains a fluorine-containing compound in a portion on the magnetic layer side of a non-magnetic support, and the ratio [theta] r of a water contact angle measured on the surface of the magnetic layer after sliding with a magnetic head to a water contact angle measured on the surface of the magnetic layer before sliding with the magnetic head is 0.70 or more. The invention also discloses a tape cartridge and a tape device comprising the tape. 本发明的课题在于提供一种即使反复行进电磁转换特性的劣化也较少的磁带。一种具有非磁性支撑体和含有强磁性粉末的磁性层的磁带。上述磁带在非磁性支撑体上的磁性层侧的部分含有含氟化合物，在与磁头滑动之后在上述磁性层的表面上测定的水接触角和在与磁头滑动之前在上述磁性层的表面上测定的水接触角的比率θr为0.70以上。一种包含上述磁带的磁带盒及磁带装置。
