Magnetic head and magnetic recording and reproducing device

A magnetic head, comprising:

• a magnetic pole;
• a first shield region, a direction from the magnetic pole toward the first shield region being aligned with a first direction;
• a second shield region, a direction from the magnetic pole toward the second shield region crossing the first direction;
• and
• a first stacked body provided between the magnetic pole and the second shield region,
• the first stacked body including
• a first 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 first magnetic layer and being provided between the magnetic pole and the first magnetic layer, and
• a second conductive layer contacting the first magnetic layer and the second shield region and being provided between the first magnetic layer and the second shield region.

A magnetic head, comprising:

• a magnetic pole;
• a first shield region;
• a second shield region;
• a third shield region, a direction from the third shield region toward the second shield region crossing a first direction from the magnetic pole toward the first shield region, at least a portion of the magnetic pole being provided between the third shield region and the second shield region in the direction from the third shield region toward the second shield region;
• a first stacked body provided between the magnetic pole and the second shield region;
• and
• a second stacked body provided between the magnetic pole and the third shield region,
• the first stacked body including
• a first magnetic layer including at least one selected from the group consisting of Fe, Co, and Ni,
• a first conductive layer provided between the magnetic pole and the first magnetic layer, and
• a second conductive layer provided between the first magnetic layer and the second shield region,
• the second stacked body including
• a second magnetic layer including at least one selected from the group consisting of Fe, Co, and Ni,
• a third conductive layer provided between the magnetic pole and the second magnetic layer, and
• a fourth conductive layer provided between the second magnetic layer and the third shield region.
