Energy-assisted magnetic-recording head having a magnetic-recording assistance element disposed to lower magnetic-recording field for reversing magnetization in a magnetic-recording disk
Energy-assisted magnetic-recording head having a magnetic-recording assistance element disposed to lower magnetic-recording field for reversing magnetization in a magnetic-recording disk
A head-slider configured to fly in proximity to a recording surface of a magnetic-recording disk. The head-slider includes a write element including a main pole configured to generate a magnetic-recording field from a pole tip of the main pole in a first localized portion of the magnetic-recording disk. The head-slider also includes a magnetic-recording assistance element configured to provide energy to a second localized portion of the magnetic-recording disk in order to increase reversibility of a magnetization in a first localized portion of the magnetic-recording disk. A width of the pole tip of the main pole on a leading-edge side is wider than a width of the pole tip of the main pole on a trailing-edge side.
