MAGNETIC HEAD AND MAGNETIC RECORDING AND REPRODUCING DEVICE
First Claim
1. A magnetic head, comprising:
- a magnetic pole having a first surface;
a first shield separated from the magnetic pole along a first direction aligned with the first surface; and
a stacked body provided between the magnetic pole and the first shield,the stacked body includinga magnetic layer including at least one selected from the group consisting of Fe, Co, and Ni,a first conductive layer contacting the magnetic pole and the magnetic layer, being provided between the magnetic pole and the magnetic layer, and being nonmagnetic, anda second conductive layer contacting the magnetic layer and the first shield, being provided between the magnetic layer and the first shield, and being nonmagnetic,the first shield having a first shield surface contacting the second conductive layer,a first ratio of a length of the magnetic layer along a second direction to a length of the first shield surface along the second direction being 0.1 or more, the second direction being perpendicular to the first surface.

Abstract
According to one embodiment, a magnetic head includes a magnetic pole having a first surface, a first shield separated from the magnetic pole along the first surface, and a stacked body provided between the magnetic pole and the first shield. The stacked body includes a magnetic layer, and first and second conductive layers. The magnetic layer includes at least one selected from the group consisting of Fe, Co, and Ni. The first conductive layer contacts the magnetic pole and the magnetic layer, and is provided between the magnetic pole and the magnetic layer. The second conductive layer contacts the magnetic layer and the first shield, is provided between the magnetic layer and the first shield. The first shield has a first shield surface contacting the second conductive layer. A ratio of a length of the magnetic layer to a length of the first shield surface is 0.1 or more.
