1. A magnetic tape comprising:

  • a non-magnetic support;

    a magnetic layer including ferromagnetic powder and a binder formed on the non-magnetic support,wherein the magnetic layer includes a timing-based servo pattern, andan edge shape of the timing-based servo pattern specified by a magnetic force microscope observation is a shape in which a difference, l99.9

    l0.1, between a value l99.9 of a cumulative frequency function of 99.9% of a position deviation width from an ideal shape in a longitudinal direction of the magnetic tape and a value l0.1 of the cumulative frequency function of 0.1% is equal to or smaller than 180 nm.
