Abstract: A manufacturing method for a magnetic head forms a leading shield having a top surface. The top surface of the leading shield includes first and second portions. The second portion is located farther from a medium facing surface than is the first portion, and recessed from the first portion. A first gap layer is then formed on the first portion. Then, a magnetic layer including an initial first side shield, an initial second side shield and a coupling section connecting them is formed using a mold. The mold is then removed. The coupling section is then removed by etching the magnetic layer. A second gap layer and a main pole are then formed in this order.

Abstract: The perpendicular magnetic recording head includes: a magnetic pole including an end surface exposed on an air bearing surface, and extending in a height direction perpendicular to the air bearing surface; a leading shield including an end surface exposed on the air bearing surface; a leading gap provided between the magnetic pole and the leading shield; and a recess shield including a mid-part and other parts, and provided at a position on a side opposite to the magnetic pole with the leading shield in between, the mid-part being distanced from the leading shield in a track width direction, the other parts being in contact with the leading shield, and the position being recessed from the air bearing surface.
