Abstract
The magnetic tape in which an absolute friction value measured with a lateral force microscope in a measurement region of 3 μm×3 μm on a surface of the magnetic layer before 500 reciprocating slides with respect to an LTO 8 head at a head tilt angle of 15° in an environment of a temperature of 15° C. and a relative humidity of 80% is 0.10 nN or less, and a reduction rate of standard deviation of friction distribution measured with the lateral force microscope in the measurement region of 3 μm×3 μm on the surface of the magnetic layer before and after the 500 reciprocating slides with respect to the LTO 8 head at the head tilt angle of 15° in the environment of the temperature of 15° C. and the relative humidity of 80% is 20% or more.
