Magnetic tape having characterized magnetic layer and magnetic tape device
Abstract:
A magnetic tape includes a magnetic layer having ferromagnetic powder and a binder on a non-magnetic support. The total thickness of the magnetic tape is less than equal to 5.30 μm. The magnetic layer includes a timing-based servo pattern. The center line average surface roughness Ra measured regarding the surface of the magnetic layer is less than or equal to 1.8 nm. One or more components selected from a fatty acid and a fatty acid amide are included in the magnetic layer, and 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 greater than or equal to 45 atom %.
