Magnetic tape device and magnetic reproducing method

A magnetic reproducing method comprising:

• reproducing information recorded on a magnetic tape by a reproducing head,
• wherein the reproducing head is a magnetic head including a tunnel magnetoresistance effect type element as a reproducing element,
• the magnetic tape includes a non-magnetic support, and a magnetic layer including ferromagnetic powder and a binding agent on the non-magnetic support,
• the ferromagnetic powder is ferromagnetic hexagonal ferrite powder,
• an intensity ratio Int(110)/Int(114) of a peak intensity Int(110) of a diffraction peak of a (110) plane with respect to a peak intensity Int(114) of a diffraction peak of a (114) plane of a hexagonal ferrite crystal structure obtained by an X-ray diffraction analysis of the magnetic layer by using an In-Plane method is 0.5 to 4.0,
• a vertical direction squareness ratio of the magnetic tape is 0.65 to 1.00,
• a center line average surface roughness Ra measured regarding a surface of the magnetic layer is equal to or smaller than 2.0 nm,
• the magnetic layer includes one or more components selected from the group consisting of fatty acid and fatty acid amide, and
• a C—H derived C concentration calculated from a C—H peak area ratio of C1s spectra obtained by X-ray photoelectron spectroscopic analysis performed on the surface of the magnetic layer at a photoelectron take-off angle of 10 degrees is 45 to 65 atom %.
