MAGNETIC HEAD FOR PERPENDICULAR MAGNETIC RECORDING HAVING MAIN POLE AND TWO SHIELDS

摘要

PROBLEM TO BE SOLVED: To shorten the length of a magnetic path that passes through a main pole and a shield disposed forward of the main pole along the direction of travel of a recording medium.

SOLUTION: A magnetic head includes: a coil; a main pole 15; a first shield 16A disposed backward of the main pole 15 along a direction of travel of a recording medium; a first return path section connecting the first shield 16A to the main pole 15; a second shield 16D disposed forward of the main pole 15 along the direction of travel of the recording medium; and a second return path section connecting the second shield 16D to the main pole 15. The second return path section includes a yoke layer 40 in contact with the main pole 15. The coil includes at least one coil element that passes between the second shield 16D and the yoke layer 40.
