Abstract
Provided is a magnetic tape, in which, in an environment of a temperature of 32° C. and a relative humidity of 80%, a frictional force F45° on a magnetic layer surface with respect to an LTO8 head measured at a head tilt angle of 45° is 4 gf or more and 15 gf or less, and standard deviation of a frictional force F on the magnetic layer surface with respect to the LTO8 head measured at each of head tilt angles of 0°, 15°, 30°, and 45° is 10 gf or less. A magnetic tape cartridge and a magnetic tape apparatus include the magnetic tape.
