PROBLEM TO BE SOLVED: To provide a head for thermally-assisted recording that includes a semiconductor laser mounted so as not to increase the overall height of the head and cause optical power variation due to wavelength fluctuation, and suppresses temperature increase of the mounted semiconductor laser.SOLUTION: A semiconductor laser 30 is placed on a side surface different from side surfaces on an inflow end side and an outflow end side, of four side surfaces of a floating slider 5. An entrance 16 of a waveguide 3 is placed on the side surface of the floating slider, to make the emitted light from the semiconductor laser directly incident upon the waveguide. A curved line part or a reflective mirror is formed in the middle of the waveguide so that the light incident upon the waveguide travels toward a near-field light generating element 1. |
