Abstract:
1. A thin film magnetic head, comprising: a main magnetic pole layer, and a trailing shield positioned closer to a trailing side than the main magnetic pole layer, wherein the trailing shield comprises a first trailing shield that is close to the main magnetic pole layer, and a second trailing shield that is positioned to be closer to the trailing side than the first trailing shield and that continues to the first trailing shield; the second trailing shield comprises a first end surface that is connected to a trailing-side end surface of the first trailing shield, and a second end surface that continues to an end side positioned at a back side in a height direction out of the end sides configuring the first end surface; the second end surface comprises a first end side positioned closest to a medium opposing surface, and a second end side positioned at the farthest back side in the height direction, and closer to the trailing side than the first end side; an angle formed by a virtual plane including the first end side and the second end side relative to a plane parallel to both the height direction and the track width direction is 30 degrees to 60 degrees, and the first trailing shield comprises a first end surface forming a portion of the medium opposing surface, and a second end surface that is parallel to the first end surface, and that is positioned at the back side in the height direction.
