Magnetic recording write head having YIG-heavy metal-YIG in write gap
Western Digital Technologies, Inc., San Jose, CA, has been assigned a patent (10,734,015) developed by Song, Suping, Fremont, CA, Li, Zhanjie, Pleasanton, CA, and Ho, Michael Kuok San, Emerald Hills, CA, for a “magnetic recording write head having YIG-heavy metal-YIG in write gap and side gap to maximize spin-orbit-coupling efficiency.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a main pole at a media facing surface, MFS, a trailing shield at the MFS, a heavy metal layer disposed between the main pole and the trailing shield at the MFS, and a yttrium-iron garnet (YIG) layer. Spin-orbit torque (SOT) is generated from the heavy metal layer and transferred to a surface of the main pole as a current passes through the heavy metal layer in a cross-track direction. The YIG layer is an electrical insulator, but also a good spin current conductor. Thus the charge current can be fully utilized for spin current conversion. The YIG layer does not dissipate energy because there is no shunting. With the reduced shunting from the main pole to the trailing shield, write-ability is improved.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a main pole at a media facing surface, MFS, a trailing shield at the MFS, and a heavy metal layer disposed between the main pole and the trailing shield at the MFS. Spin-orbit torque (SOT) is generated from the heavy metal layer and transferred to a surface of the main pole as a current passes through the heavy metal layer in a cross-track direction. The SOT executes a torque on the surface magnetization of the main pole, which reduces the magnetic flux shunting from the main pole to the trailing shield. With the reduced magnetic flux shunting from the main pole to the trailing shield, write-ability is improved.”
