Electromagnetic field generating element, information recording and reproduction head, and information recording and reproduction device
Abstract:
An electromagnetic field generating element includes a conductor that generates near-field light when irradiated with light and generates a magnetic field when a current flows through the conductor. The electromagnetic field generating element further includes a soft magnetic body provided at a position along a dimension of the conductor, the dimension being perpendicular to (i) a direction in which the conductor faces a magnetic recording medium to which the near-field light and the magnetic field are applied and to (ii) a direction in which the current flows. The present invention thus allows for provision of an electromagnetic field generating element that allows for reduction in its power consumption in optically assisted magnetic read/write using near-field light.
