A perpendicular magnetic recording head and a method of manufacturing the same are provided. The perpendicular magnetic recording head that includes a main pole, a return yoke, and coils that surround upper and lower parts of the main pole in a solenoid shape so that the main pole generates a magnetic field for recording information onto a recording medium, wherein a portion of the coils that pass above the main pole comprises a plurality of first coils and at least one second coil having a cross-sectional shape different from that of the first coils, and the second coil is formed across upper regions of two first coils adjacent to each other among the first coils.

Perpendicular magnetic recording head having coil portions above a main pole and provided with different cross-sectional shapes and method of manufacturing the same

A method of servo writing for each track of a magnetic recording medium divided into a plurality of circular tracks including performing a phase adjustment operation by controlling a phase of a recording current according to a skew angle formed by a magnetic head and a track of the magnetic recording medium, and writing a servo pattern when the magnetic recording medium is magnetized using a magnetic head so as to have a magnetized pattern corresponding to a servo pattern.
