Magnetic tape apparatus

A magnetic tape apparatus comprising:

• a magnetic tape;
• a reading element unit;
• and
• an extraction unit,
• wherein the magnetic tape includes a non-magnetic support, and a magnetic layer including a ferromagnetic powder and a binding agent on the non-magnetic support,
• 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 a surface of the magnetic layer at a photoelectron take-off angle of 10 degrees is equal to or greater than 45 atom %,
• the magnetic tape includes one or more kinds of component selected from the group consisting of fatty acid and fatty acid amide in a portion of the magnetic layer side on the non-magnetic support,
• the reading element unit includes a plurality of reading elements each of which reads data by a linear scanning method from a specific track region including a reading target track in a track region included in the magnetic tape, and
• the extraction unit performs a waveform equalization process according to a deviation amount between positions of the magnetic tape and the reading element unit, with respect to each reading result for each reading element, to extract data derived from the reading target track from the reading result.
