Magnetic head for perpendicular magnetic recording and method of manufacturing same
摘要：
A magnetic head comprises a pole layer, a gap layer, a shield layer, a nonmagnetic layer, and a coil. The shield layer incorporates: a first layer disposed on the gap layer; a second layer disposed on the first layer; a two-layered coupling layer disposed on a region of the pole layer where an opening of the gap layer is formed; and a third layer disposed to couple the second layer to the coupling layer. The first layer defines throat height TH. The nonmagnetic layer is disposed on a side of the first layer. The coil is disposed on the nonmagnetic layer on a side of the second layer.
摘要（中）：

磁头包括极层，间隙层，屏蔽层，非磁性层和线圈。 屏蔽层包括：设置在间隙层上的第一层; 设置在所述第一层上的第二层; 设置在形成间隙层的开口的极层的区域上的双层结合层; 以及设置成将所述第二层耦合到所述耦合层的第三层。 第一层定义喉咙高度TH。 非磁性层设置在第一层的一侧。 线圈设置在第二层一侧的非磁性层上。
