Abstract
Provided is a magnetic tape apparatus. During running of a magnetic tape in the magnetic tape apparatus, an angle θ formed by an axis of an element array of a magnetic head with respect to a width direction of the magnetic tape is changed. The magnetic tape satisfies Expression 1, the Equation 1: TDSage+TDSenv−TC≤0.10 μm. In Expression 1, TDSage is a maximum value of an absolute value of a difference between a servo band interval obtained before storage and a servo band interval obtained after the storage in a predetermined environment for 36 hours. TDSenv is a value calculated by multiplying a difference between a maximum value and a minimum value in the servo band intervals obtained in each of predetermined five environments by ½, and TC is a value calculated by TC=L{cos(θ−Δθ)−cos(θ+Δθ)}.
