Abstract:
In order to prevent deterioration of floating characteristics of a slider due to deformation of a slider floating surface by thermal expansion of a coil, the followings are performed. A recessed portion is formed in a part of the slider, and a device for generating an optical near-field and the coil for generating a magnetic field are formed in the recessed portion. The optical near-field generation device is formed on a surface facing a recording medium, and the magnetic field application coil is formed on an upper surface of the recessed portion. The optical near-field generation device and the magnetic field application coil are respectively exposed to the surface.
