Magnetic tape having characterized magnetic layer surface, magnetic tape cartridge, and magnetic tape device

A magnetic tape comprising:

• a non-magnetic support;
• and
• a magnetic layer containing a ferromagnetic powder,
• wherein
• the non-magnetic support is polyethylene terephthalate, polyethylene naphthalate, or polyamide,
• one or more kinds of component selected from the group consisting of a fatty acid and a fatty acid amide are included in a portion on a magnetic layer side of the non-magnetic support,
• a C—H derived C concentration calculated from a C—H peak surface area ratio in C1s spectra obtained by X-ray photoelectron spectroscopy performed on a surface of the magnetic layer at a photoelectron take-off angle of 10 degrees is 45 atom % to 65 atom %, and
• in an environment with a temperature of 23° C. and a relative humidity of 50%,
• an AlFeSil abrasion value45° of the surface of the magnetic layer measured at a tilt angle of 45° of an AlFeSil prism is 20 μm to 50 μm,
• a standard deviation of an AlFeSil abrasion value of the surface of the magnetic layer measured at each of tilt angles of 0°, 15°, 30°, and 45° of the AlFeSil prism is 30 μm or less, and
• the tilt angle of the AlFeSil prism is an angle formed by a longitudinal direction of the AlFeSil prism and a width direction of the magnetic tape.
