Magnetic tape having characterized magnetic layer, magnetic tape cartridge, and magnetic tape apparatus

A magnetic tape comprising:

• a non-magnetic support;
• a magnetic layer containing a ferromagnetic powder, and
• a non-magnetic layer containing a non-magnetic powder between the non-magnetic support and the magnetic layer,
• wherein one or more components selected from the group consisting of a fatty acid and a fatty acid amide are included in a portion on the non-magnetic support on a magnetic layer side,
• a C—H derived C concentration calculated from a C—H peak surface area ratio of 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 50 at % or more,
• standard deviation σ of the C—H derived C concentration in a width direction of the surface of the magnetic layer is 2.0 at % or less,
• a fluorine-containing compound is included in the portion on the non-magnetic support on the magnetic layer side,
• the non-magnetic powder includes an Fe-based inorganic oxide powder having an average particle volume of 2.0×10−6 μm3 or less, and
• the non-magnetic powder includes carbon black having a pH of 9.0 or less.
