Magnetic tape and method of manufacturing the same

A method of manufacturing a magnetic tape,

• wherein the magnetic tape 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 at least the magnetic layer comprises one or more components selected from the group consisting of a fatty acid and a fatty acid amide;
• a quantity of components selected from the group consisting of a fatty acid and a fatty acid amide per unit area of the magnetic tape among components that are extracted from a surface on the magnetic layer side of the magnetic tape is less than or equal to 15.0 mg/m2, the extraction being conducted by immersion of a 5 cm sample of the magnetic tape with heating in 30 mL of methanol for 3 hours at 60° C., and
• a concentration of carbon, C, that is obtained by X-ray photoelectron spectroscopy conducted at a photoelectron take-off angle of 10 degrees on the surface on the magnetic layer side of the magnetic tape is greater than or equal to 50 atom %, and
• the method comprises a step of forming a nonmagnetic layer and a step of forming a magnetic layer, wherein the step of forming the nonmagnetic layer comprises:
• a coating step of forming a coating layer by coating on a nonmagnetic support a nonmagnetic layer forming composition comprising one or more components selected from the group consisting of a fatty acid and a fatty acid amide, nonmagnetic powder, binder, and solvent;
• a heating and drying step of drying the coating layer by a heat treatment;
• and
• the step of forming the nonmagnetic layer further comprises, between the coating step and the heating and drying step, a cooling step of cooling the coating layer.
