Abstract:
The magnetic tape has a magnetic layer containing ferromagnetic powder and binder on a nonmagnetic support, wherein the coercive force measured in the longitudinal direction of the magnetic tape is less than or equal to 167 kA/m, a timing-based servo pattern is present on the magnetic layer, and the edge shape specified by observing the timing-based servo pattern with a magnetic force microscope is a shape in which the difference between the value L99.9 of the 99.9% cumulative distribution function of the width of misalignment from the ideal shape in the longitudinal direction of the magnetic tape and the value L0.1 of the 0.1% cumulative distribution function, L99.9−L0.1, is less than or equal to 180 nm.
