Servo pattern recording device, magnetic tape, magnetic tape cartridge, magnetic tape drive, magnetic tape system, detection device, servo pattern recording method, and manufacturing method of magnetic tape

A servo pattern recording head, comprising:

• a substrate;
• and
• a plurality of gap patterns formed on a front surface of the substrate,
• wherein the plurality of gap patterns are formed on the front surface along a direction corresponding to the width direction,
• the servo pattern recording head is configured to record a plurality of servo patterns in the width direction by applying a magnetic field to a magnetic tape in response to a supplied pulse signal,
• the gap patterns are at least one straight line region pair,
• a first straight line region, which is one straight line region of the straight line region pair, and a second straight line region, which is the other straight line region of the straight line region pair, are inclined in opposite directions with respect to a first imaginary straight line along the direction corresponding to the width direction on the front surface,
• the first straight line region has a steeper inclined angle with respect to the first imaginary straight line than the second straight line region,
• positions of both ends of the first straight line region and positions of both ends of the second straight line region are aligned in the direction corresponding to the width direction of the magnetic tape,
• the plurality of gap patterns deviate from each other at a predetermined interval in a direction corresponding to a longitudinal direction of the magnetic tape, between the gap patterns adjacent to each other along the direction corresponding to the width direction, and
• the substrate is inclined along the magnetic tape with respect to the first imaginary straight line at an angle at which deviation at the predetermined interval is absorbed.
