Patent ID: 8446691

Claim:
A magnetic recording device comprising: a magnetic recording head including: a main magnetic pole having a medium facing surface and a main magnetic pole side surface intersecting the medium facing surface, a main magnetic pole including a soft magnetic material, and configured to generate a recording magnetic field; a shield having a shield side surface facing the main magnetic pole side surface; a stacked structure provided between the main magnetic pole and the shield, the stacked structure including: a first magnetic layer; a second magnetic layer; and an intermediate layer provided between the first magnetic layer and the second magnetic layer and including a nonmagnetic material; and a magnetic recording medium including: a backing layer including a soft magnetic material and forming a magnetic circuit together with the main magnetic pole and the shield; and a magnetic recording layer provided between the backing layer and the magnetic recording head, having a major surface, the major surface facing the medium facing surface and the shield, and subjected to perpendicular magnetic recording by the recording magnetic field, a first distance along a direction perpendicular to the major surface between an end portion of the medium facing surface on a side of the stacked structure and the backing layer being twice or more of a second distance along a direction perpendicular to the main magnetic pole side surface between the main magnetic pole side surface and the shield side surface.
