Magnetic head for perpendicular magnetic recording with shield around main pole
A magnetic head includes a shield, and first and second return path sections. The shield has an end face that is located in a medium facing surface to wrap around an end face of a main pole. The shield includes a bottom shield, two side shields, and a top shield. The first return path section is magnetically connected to the bottom shield and is greater than the bottom shield in length in a direction perpendicular to the medium facing surface. The second return path section magnetically couples the top shield and the main pole to each other. The coil includes a first portion that passes through a space defined by the main pole and the first return path section, and a second portion that passes through a space defined by the main pole and the second return path section.
