A magnetic recording apparatus includes a disk-shaped recording medium with a magnetic recording layer, and a recording head that magnetically writes data onto the magnetic recording layer and includes a main magnetic pole, a write shield facing the main magnetic pole and positioned with a writing gap disposed between the main magnetic pole and the write shield, and a magnetic flux control layer disposed inside the write gap between the main magnetic pole and the writing shield. The magnetic flux control layer includes a first layer including a first metal and contacting one of the main magnetic pole and the writing shield, a second control layer, and a third layer including a second metal and contacting the other one of the main magnetic pole and the writing shield. The second control layer includes a magnetic metal and contacts the first layer and the third layer.

According to one embodiment, a magnetic head includes a magnetic pole, and a first shield, and a stacked body provided between the magnetic pole and the first shield. The stacked body includes a first layer, a second layer and a third layer. The first layer includes at least one first element selected from the group consisting of Fe, Co, and Ni. The second layer is provided between the magnetic pole and the first layer, and includes at least one second element selected from the group consisting of Cr, V, Mn, Ti, and Sc. The third layer is provided between the first layer and the first shield, and includes at least one third element selected from the group consisting of Cr, V, Mn, Ti, and Sc.

The present disclosure generally relates to a magnetic recording head comprising a spintronic device. By electrically coupling the side shielding of the head (acting as current leads) to the spin Hall layer of the spintronic device, the current path length is optimally provided across the spin Hall layer as well as fitting within the space constraints of the overall head. In addition, by using an antiferromagnetic insulator as a spacer between the spin Hall layer and the magnetic spin torque layer of the spintronic device, electrically shunting into the magnetic spin torque layer is reduced, maximizing the spin torque and reducing loss of efficiency due to shunting. Thus, the magnetic recording head may utilize the energy assistance from the spintronic device without reducing the quality and reliability of the write head by running an undesirable current through critical components of the write head.

A write head for recording data on a storage medium. The write head includes a bearing surface and a write pole. The write pole includes a main pole layer having a front surface that forms a portion of the bearing surface. The front surface of the write pole has a leading edge and a trailing edge. The write pole further includes a high damping material layer. The high damping material layer has a front end that is attached to the main pole layer at the leading edge.

The present disclosure generally relates to a spin torque element disposed between a main pole and a shield in a magnetic recording head. The shield could be a trailing shield, a side shield, or a leading shield. The spin torque element includes a dual layer spin transfer structure that is spaced from magnetic layers on either side using spacer layers. One magnetic layer that faces a positive polarizer has a positive polarization while another magnetic layer facing the negative polarizer has a negative polarization. As such, torque in the spacer layers is maximized when the direction of the magnetization in the STL is opposite to the gap field.
