Summary:Embodiments of the present invention provide a magnetic head slider capable of reducing thermal protrusion attributable to a heating mechanism for heat-assisted recording. According to one embodiment, a magnetic head slider for heat-assisted recording includes an insulating film formed on an end surface of a slider, and a read element, a write device and a heating mechanism for heating a recording medium embedded in the insulating film. The heating mechanism includes an optical waveguide and a near-field light emitting device. A heat radiating film of a material having a thermal conductivity higher than that of the insulating film is formed near the heating mechanism so that one end surface thereof is exposed in an air bearing surface.
