A magnetic tape apparatus, in which a magnetic tape includes a servo pattern in a magnetic layer, ΔSFD in a longitudinal direction of the magnetic tape is equal to or smaller than 0.50, a 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, an 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, and the deviation amount is determined in accordance with a result obtained by reading of the servo pattern included in the magnetic layer of the magnetic tape by a servo element.
