Claim:
1. A magnetic tape, which comprises on one surface of a nonmagnetic support a magnetic layer comprising ferromagnetic powder and binder, and on the other surface of the nonmagnetic support, a backcoat layer comprising nonmagnetic powder and binder, wherein a total thickness of the magnetic tape is less than or equal to 4.80 μm, the backcoat layer comprises one or more components selected from the group consisting of a fatty acid and a fatty acid amide, and a C—H derived carbon, C, concentration calculated from a C—H peak area ratio in a C1s spectrum obtained by X-ray photoelectron spectroscopy conducted at a photoelectron take-off angle of 10 degrees on a surface on the backcoat layer side of the magnetic tape ranges from 35 to 60 atom %.
