Summary: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 plurality of gap patterns are formed on a surface of a substrate along a direction corresponding to a width direction of a magnetic tape. A first straight line area is inclined at a steeper angle with respect to a first virtual straight line than a 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 the width direction of the magnetic tape. Positions of the plurality of gap patterns are aligned in a longitudinal direction of the magnetic tape. The plurality of gap patterns are supplied with pulse signals with a delay by a prescribed time from one side to the other side of a direction in which the plurality of gap patterns are arranged.SELECTED DRAWING: Figure 18 【課題】信頼性の高いサーボ信号を得ることができるサーボパターン記録装置、磁気テープ、磁気テープカートリッジ、磁気テープドライブ、磁気テープシステム、検出装置、検査装置、サーボパターン記録方法、磁気テープの製造方法、検出方法、及び検査方法を提供する。【解決手段】複数のギャップパターンは、磁気テープの幅方向に対応する方向に沿って基体の表面に形成されている。第１直線領域は、第２直線領域よりも、第１仮想直線に対する傾斜角度が急である。第１直線領域の両端の位置と第２直線領域の両端の位置とが磁気テープの幅方向に対応する方向で揃っている。複数のギャップパターンは、磁気テープの長手方向での位置が揃っている。複数のギャップパターンの各々には、複数のギャップパターンが配列されている方向の一方の側から他方の側にかけてパルス信号が既定時間ずつ遅れて供給される。【選択図】図１８
