Abstract:
A magnetic tape includes a non-magnetic layer containing non-magnetic powder and a binder on a non-magnetic support; and a magnetic layer containing ferromagnetic powder and a binder on the non-magnetic layer. The total thickness of the non-magnetic layer and the magnetic layer is equal to or less than 0.60 μm. The magnetic layer includes a timing-based servo pattern. One or more components selected from a fatty acid and a fatty acid amide are included in at least the magnetic layer. The C—H derived C concentration calculated from the 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 equal to or greater than 45 atom %.
