Summary:Provided is a magnetic tape, in which, in an environment with a temperature of 23° C. and a relative humidity of 50%, an AlFeSil abrasion value45° of a surface of the magnetic layer, which is measured at a tilt angle of 45° of an AlFeSil square bar, is 20 μm or more and 50 μm or less, and standard deviation of AlFeSil abrasion values of the surface of the magnetic layer, which are respectively measured at tilt angles of 0°, 15°, 30°, and 45° of the AlFeSil square bar, is 30 μm or less. The tilt angle of the AlFeSil square bar is an angle formed by a longitudinal direction of the AlFeSil square bar and a width direction of the magnetic tape. The magnetic tape includes a polyethylene naphthalate support having a Young's modulus in a width direction of 10000 MPa or more.
