Abstract
The aim of the present invention is to apply an intense magnetic field to a portion where an optical near-field is generated by a thermal assisted magnetic recording head with a scatterer having conductivity as an optical near-field generating element. To this end, a scatterer for generating an optical near-field is formed in a bottom portion of a slider, and a magnetic field is applied thereto using a coil. In order to increase the intensity of the magnetic field, a magnetic pole made of a soft magnetic material is formed over the scatterer.
