1. A magnetic tape comprising:
a timing-based servo pattern,
wherein the magnetic tape is used in a magnetic tape device in which a total number of data tracks is 8705 or more in conversion of a magnetic tape having a width of ½ inches,
ΔPNL of the timing-based servo pattern is 10.0% or less of a track pitch, and
the ΔPNL indicates an amount of deviation of the timing-based servo pattern from linearity.
