Abstract: Provided is a magnetic tape, in which servo patterns, each including a first magnetization region formed to be tilted with respect to a width direction of a servo band by an angle θ along the width direction of the servo band and a second magnetization region not parallel to the first magnetization region along the width direction of the servo band, are repeatedly formed in a longitudinal direction of the servo band, the magnetic tape is used in a recording and reproducing system which uses a reproducing element for reproducing the servo pattern, a width of which satisfies W1≤(1/tan θ)×stripe width T of the servo pattern, and the angle θ is greater than 25° and equal to or smaller than 45°.
