Application Number: JP,2022-126244
Category (FI): G11B5/31@E,G11B5/02@R,G11B5/31@A
Stage: PROBLEM TO BE SOLVED: To provide a magnetic head and a magnetic recording device capable of improving recording density.SOLUTION: According to an embodiment, a magnetic head includes a first magnetic pole, a second magnetic pole, and a laminated body. The first magnetic pole includes a first surface and a second surface intersecting the first surface. The second surface includes a first surface region. The second magnetic pole includes a third surface and a fourth surface intersecting the third surface. The fourth surface includes a second surface region. A direction from the first surface region to the second surface region is along a first direction. The first surface region and the second surface region are along a second direction and a third direction. The first surface and the third surface are along the third direction. The laminated body is provided between the first surface region and the second surface region. The laminated body includes a first magnetic layer and a second magnetic layer. The second magnetic layer includes a second magnetic layer surface opposite to the second surface region. A width ratio of a second width along the third direction of the second magnetic layer surface to a first width along the third direction of the first surface area is 0.25 or more and 0.92 or less.SELECTED DRAWING: Figure 1 (Grant)
