Abstract
The magnetic tape includes a non-magnetic support, and a magnetic layer containing a ferromagnetic powder. A rate of change in an area ratio of a protrusion having a height of 5 nm or more and 10 nm or less, which is obtained by measuring a measurement region of 5 μm×5 μm on a surface of the magnetic layer before and after 1000 reciprocating slides with respect to an LTO 8 head at a head tilt angle of 15° in an environment of a temperature of 35° C. and a relative humidity of 80%, with an atomic force microscope, is 10.0% or less.
