Magnetic head for perpendicular magnetic recording having a main pole and a shield

A magnetic head for perpendicular magnetic recording, comprising:

• a medium facing surface that faces a recording medium;
• a coil that produces a magnetic field corresponding to data to be written on the recording medium;
• a main pole that has an end face located in the medium facing surface, allows a magnetic flux corresponding to the magnetic field produced by the coil to pass, and produces a write magnetic field for writing the data on the recording medium by means of a perpendicular magnetic recording system;
• a write shield made of a magnetic material and having an end face located in the medium facing surface;
• a gap part made of a nonmagnetic material and disposed between the main pole and the write shield;
• and
• a first yoke layer and a second yoke layer that are aligned along a direction of travel of the recording medium such that the main pole is interposed between the first and second yoke layers, each of the first and second yoke layers being made of a magnetic material and magnetically connected to the write shield, wherein:
• the end face of the write shield includes a first end face portion located forward of the end face of the main pole along the direction of travel of the recording medium;
• and
• the coil includes a winding portion of planar spiral shape that is formed in one or more layers,
• the magnetic head further comprising:
• a first coupling part that is located away from the medium facing surface and magnetically couples the main pole and the second yoke layer to each other;
• and
• a second coupling part that is located away from the medium facing surface and magnetically couples the first yoke layer and the second yoke layer to each other without touching the main pole,
• wherein the winding portion is wound around the first coupling part, and a part of the winding portion passes between the first coupling part and the second coupling part.
