Stage: PROBLEM TO BE SOLVED: To provide a servo pattern recording device, a magnetic tape, a magnetic tape cartridge, a magnetic tape drive, a magnetic tape system, a detection device, an inspection device, a servo pattern recording method, a method for manufacturing the magnetic tape, a detection method, and an inspection method with which a highly reliable servo signal can be obtained.SOLUTION: A gap pattern is at least one straight line area pair. A first straight line area and a second straight line area of the straight line area pair are inclined in a direction opposite to a first virtual straight line. The first straight line area is inclined at a steeper angle with respect to the first virtual straight line than the second straight line area. Positions of both ends of the first straight line area and positions of both ends of the second straight line area are aligned in a direction corresponding to a width direction of a magnetic tape. A plurality of gap patterns are shifted at a prescribed interval in a direction corresponding to a longitudinal direction of the magnetic tape between the gap patterns adjacent along the direction corresponding to the width direction of the magnetic tape. A substrate is inclined with respect to the first virtual straight line at an angle to absorb the shift.SELECTED DRAWING: Figure 18 (Grant)
