Abstract:
A perpendicular magnetic recording head and a method of manufacturing said perpendicular magnetic recording head are provided. The perpendicular magnetic recording head has a main pole, a coil, which applies a magnetic field to the main pole, and a return pole constituting a magnetic circuit together with the main pole. The main pole has a back pole around which the coil is wound and a front pole contacting the back pole. The back pole and the front pole are formed on the same plane.
