发明名称 MAGNETIC STORAGE APPARATUS
摘要 A magnetic storage apparatus is provided with a perpendicular magnetic recording medium having a soft magnetic underlayer and a recording layer, and a magnetic head having a medium opposing surface. The soft magnetic underlayer has axes of easy magnetization oriented along a circumferential direction. A return yoke part of a recording element in the head includes return side yokes arranged in a radial direction of a main magnetic pole part on the medium opposing surface, whereby a magnetic flux of a recording magnetic field flows in the radial direction within the soft magnetic underlayer.
