发明名称 Magnetic tape and method of manufacturing the same
摘要 Provided is a magnetic tape, which comprises, on a nonmagnetic support, a nonmagnetic layer comprising nonmagnetic powder and binder, and on the nonmagnetic layer, a magnetic layer comprising ferromagnetic powder and binder; wherein a total thickness of the magnetic tape is less than or equal to 4.80 μm; at least the magnetic 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 magnetic layer side of the magnetic tape is greater than or equal to 45 atom %.
