Magnetic tape, magnetic tape cartridge, magnetic tape system, inspection method, and method of manufacturing magnetic tape

Abstract

Provided are a magnetic tape, a magnetic tape cartridge, a magnetic tape system, an inspection method, and a manufacturing method of a magnetic tape capable of contributing to improvement of accuracy of recording data on the magnetic tape and accuracy of reproducing data recorded on the magnetic tape.SOLUTION: The index indicating the non-linearity of the servo pattern falls within 15% or less of the track pitch. The track pitch is a pitch between tracks. The index indicates a degree of variation of the plurality of distance differences from an average value of the plurality of distance differences. The distance difference is a difference between a distance between a pair of first positions corresponding to each other in the width direction in a pair of servo patterns and a distance between a pair of second positions shifted from the pair of first positions in the width direction by a first predetermined interval in the pair of servo patterns. The plurality of distance differences are obtained by measuring the distance difference in a pair of servo patterns at each second predetermined interval along the width direction. The first predetermined interval is larger than the second predetermined interval.SELECTED DRAWING: Figure 17
