Abstract
According to one embodiment, a magnetic head for recording magnetic data by changing the magnetization direction of a magnetic recording layer of a magnetic medium comprises a magnetic pole for generating a magnetic field to change the magnetization direction of the magnetic recording layer, and a facing electrode pair for generating an electromagnetic field and applying energy to the magnetic recording layer to assist the change of the magnetization direction of the magnetic recording layer caused by the magnetic field from the magnetic pole. Other embodiments are also presented.
